Each component ++shall be described in order to understand the significance of, and reasoning for ++it. The codebase when the first stable version was released was approximately ++9000 lines less code than the existing mainline linux kernel scheduler (in ++2.6.31). This does not even take into account the removal of documentation and ++the cgroups code that is not used. ++ ++Design reasoning. ++ ++The single runqueue refers to the queued but not running processes for the ++entire system, regardless of the number of CPUs. The reason for going back to ++a single runqueue design is that once multiple runqueues are introduced, ++per-CPU or otherwise, there will be complex interactions as each runqueue will ++be responsible for the scheduling latency and fairness of the tasks only on its ++own runqueue, and to achieve fairness and low latency across multiple CPUs, any ++advantage in throughput of having CPU local tasks causes other disadvantages. ++This is due to requiring a very complex balancing system to at best achieve some ++semblance of fairness across CPUs and can only maintain relatively low latency ++for tasks bound to the same CPUs, not across them. To increase said fairness ++and latency across CPUs, the advantage of local runqueue locking, which makes ++for better scalability, is lost due to having to grab multiple locks. ++ ++A significant feature of BFS is that all accounting is done purely based on CPU ++used and nowhere is sleep time used in any way to determine entitlement or ++interactivity. Interactivity "estimators" that use some kind of sleep/run ++algorithm are doomed to fail to detect all interactive tasks, and to falsely tag ++tasks that aren't interactive as being so. The reason for this is that it is ++close to impossible to determine that when a task is sleeping, whether it is ++doing it voluntarily, as in a userspace application waiting for input in the ++form of a mouse click or otherwise, or involuntarily, because it is waiting for ++another thread, process, I/O, kernel activity or whatever. Thus, such an ++estimator will introduce corner cases, and more heuristics will be required to ++cope with those corner cases, introducing more corner cases and failed ++interactivity detection and so on. Interactivity in BFS is built into the design ++by virtue of the fact that tasks that are waking up have not used up their quota ++of CPU time, and have earlier effective deadlines, thereby making it very likely ++they will preempt any CPU bound task of equivalent nice level. See below for ++more information on the virtual deadline mechanism. Even if they do not preempt ++a running task, because the rr interval is guaranteed to have a bound upper ++limit on how long a task will wait for, it will be scheduled within a timeframe ++that will not cause visible interface jitter. ++ ++ ++Design details. ++ ++Task insertion. ++ ++BFS inserts tasks into each relevant queue as an O(1) insertion into a double ++linked list. On insertion, *every* running queue is checked to see if the newly ++queued task can run on any idle queue, or preempt the lowest running task on the ++system. This is how the cross-CPU scheduling of BFS achieves significantly lower ++latency per extra CPU the system has. In this case the lookup is, in the worst ++case scenario, O(n) where n is the number of CPUs on the system. ++ ++Data protection. ++ ++BFS has one single lock protecting the process local data of every task in the ++global queue. Thus every insertion, removal and modification of task data in the ++global runqueue needs to grab the global lock. However, once a task is taken by ++a CPU, the CPU has its own local data copy of the running process' accounting ++information which only that CPU accesses and modifies (such as during a ++timer tick) thus allowing the accounting data to be updated lockless. Once a ++CPU has taken a task to run, it removes it from the global queue. Thus the ++global queue only ever has, at most, ++ ++ (number of tasks requesting cpu time) - (number of logical CPUs) + 1 ++ ++tasks in the global queue. This value is relevant for the time taken to look up ++tasks during scheduling. This will increase if many tasks with CPU affinity set ++in their policy to limit which CPUs they're allowed to run on if they outnumber ++the number of CPUs. The +1 is because when rescheduling a task, the CPU's ++currently running task is put back on the queue. Lookup will be described after ++the virtual deadline mechanism is explained. ++ ++Virtual deadline. ++ ++The key to achieving low latency, scheduling fairness, and "nice level" ++distribution in BFS is entirely in the virtual deadline mechanism. The one ++tunable in BFS is the rr_interval, or "round robin interval". This is the ++maximum time two SCHED_OTHER (or SCHED_NORMAL, the common scheduling policy) ++tasks of the same nice level will be running for, or looking at it the other ++way around, the longest duration two tasks of the same nice level will be ++delayed for. When a task requests cpu time, it is given a quota (time_slice) ++equal to the rr_interval and a virtual deadline. The virtual deadline is ++offset from the current time in jiffies by this equation: ++ ++ jiffies + (prio_ratio * rr_interval) ++ ++The prio_ratio is determined as a ratio compared to the baseline of nice -20 ++and increases by 10% per nice level. The deadline is a virtual one only in that ++no guarantee is placed that a task will actually be scheduled by this time, but ++it is used to compare which task should go next. There are three components to ++how a task is next chosen. First is time_slice expiration. If a task runs out ++of its time_slice, it is descheduled, the time_slice is refilled, and the ++deadline reset to that formula above. Second is sleep, where a task no longer ++is requesting CPU for whatever reason. The time_slice and deadline are _not_ ++adjusted in this case and are just carried over for when the task is next ++scheduled. Third is preemption, and that is when a newly waking task is deemed ++higher priority than a currently running task on any cpu by virtue of the fact ++that it has an earlier virtual deadline than the currently running task. The ++earlier deadline is the key to which task is next chosen for the first and ++second cases. Once a task is descheduled, it is put back on the queue, and an ++O(n) lookup of all queued-but-not-running tasks is done to determine which has ++the earliest deadline and that task is chosen to receive CPU next. ++ ++The CPU proportion of different nice tasks works out to be approximately the ++ ++ (prio_ratio difference)^2 ++ ++The reason it is squared is that a task's deadline does not change while it is ++running unless it runs out of time_slice. Thus, even if the time actually ++passes the deadline of another task that is queued, it will not get CPU time ++unless the current running task deschedules, and the time "base" (jiffies) is ++constantly moving. ++ ++Task lookup. ++ ++BFS has 103 priority queues. 100 of these are dedicated to the static priority ++of realtime tasks, and the remaining 3 are, in order of best to worst priority, ++SCHED_ISO (isochronous), SCHED_NORMAL, and SCHED_IDLEPRIO (idle priority ++scheduling). When a task of these priorities is queued, a bitmap of running ++priorities is set showing which of these priorities has tasks waiting for CPU ++time. When a CPU is made to reschedule, the lookup for the next task to get ++CPU time is performed in the following way: ++ ++First the bitmap is checked to see what static priority tasks are queued. If ++any realtime priorities are found, the corresponding queue is checked and the ++first task listed there is taken (provided CPU affinity is suitable) and lookup ++is complete. If the priority corresponds to a SCHED_ISO task, they are also ++taken in FIFO order (as they behave like SCHED_RR). If the priority corresponds ++to either SCHED_NORMAL or SCHED_IDLEPRIO, then the lookup becomes O(n). At this ++stage, every task in the runlist that corresponds to that priority is checked ++to see which has the earliest set deadline, and (provided it has suitable CPU ++affinity) it is taken off the runqueue and given the CPU. If a task has an ++expired deadline, it is taken and the rest of the lookup aborted (as they are ++chosen in FIFO order). ++ ++Thus, the lookup is O(n) in the worst case only, where n is as described ++earlier, as tasks may be chosen before the whole task list is looked over. ++ ++ ++Scalability. ++ ++The major limitations of BFS will be that of scalability, as the separate ++runqueue designs will have less lock contention as the number of CPUs rises. ++However they do not scale linearly even with separate runqueues as multiple ++runqueues will need to be locked concurrently on such designs to be able to ++achieve fair CPU balancing, to try and achieve some sort of nice-level fairness ++across CPUs, and to achieve low enough latency for tasks on a busy CPU when ++other CPUs would be more suited. BFS has the advantage that it requires no ++balancing algorithm whatsoever, as balancing occurs by proxy simply because ++all CPUs draw off the global runqueue, in priority and deadline order. Despite ++the fact that scalability is _not_ the prime concern of BFS, it both shows very ++good scalability to smaller numbers of CPUs and is likely a more scalable design ++at these numbers of CPUs. ++ ++It also has some very low overhead scalability features built into the design ++when it has been deemed their overhead is so marginal that they're worth adding. ++The first is the local copy of the running process' data to the CPU it's running ++on to allow that data to be updated lockless where possible. Then there is ++deference paid to the last CPU a task was running on, by trying that CPU first ++when looking for an idle CPU to use the next time it's scheduled. Finally there ++is the notion of cache locality beyond the last running CPU. The sched_domains ++information is used to determine the relative virtual "cache distance" that ++other CPUs have from the last CPU a task was running on. CPUs with shared ++caches, such as SMT siblings, or multicore CPUs with shared caches, are treated ++as cache local. CPUs without shared caches are treated as not cache local, and ++CPUs on different NUMA nodes are treated as very distant. This "relative cache ++distance" is used by modifying the virtual deadline value when doing lookups. ++Effectively, the deadline is unaltered between "cache local" CPUs, doubled for ++"cache distant" CPUs, and quadrupled for "very distant" CPUs. The reasoning ++behind the doubling of deadlines is as follows. The real cost of migrating a ++task from one CPU to another is entirely dependant on the cache footprint of ++the task, how cache intensive the task is, how long it's been running on that ++CPU to take up the bulk of its cache, how big the CPU cache is, how fast and ++how layered the CPU cache is, how fast a context switch is... and so on. In ++other words, it's close to random in the real world where we do more than just ++one sole workload. The only thing we can be sure of is that it's not free. So ++BFS uses the principle that an idle CPU is a wasted CPU and utilising idle CPUs ++is more important than cache locality, and cache locality only plays a part ++after that. Doubling the effective deadline is based on the premise that the ++"cache local" CPUs will tend to work on the same tasks up to double the number ++of cache local CPUs, and once the workload is beyond that amount, it is likely ++that none of the tasks are cache warm anywhere anyway. The quadrupling for NUMA ++is a value I pulled out of my arse. ++ ++When choosing an idle CPU for a waking task, the cache locality is determined ++according to where the task last ran and then idle CPUs are ranked from best ++to worst to choose the most suitable idle CPU based on cache locality, NUMA ++node locality and hyperthread sibling business. They are chosen in the ++following preference (if idle): ++ ++* Same core, idle or busy cache, idle threads ++* Other core, same cache, idle or busy cache, idle threads. ++* Same node, other CPU, idle cache, idle threads. ++* Same node, other CPU, busy cache, idle threads. ++* Same core, busy threads. ++* Other core, same cache, busy threads. ++* Same node, other CPU, busy threads. ++* Other node, other CPU, idle cache, idle threads. ++* Other node, other CPU, busy cache, idle threads. ++* Other node, other CPU, busy threads. ++ ++This shows the SMT or "hyperthread" awareness in the design as well which will ++choose a real idle core first before a logical SMT sibling which already has ++tasks on the physical CPU. ++ ++Early benchmarking of BFS suggested scalability dropped off at the 16 CPU mark. ++However this benchmarking was performed on an earlier design that was far less ++scalable than the current one so it's hard to know how scalable it is in terms ++of both CPUs (due to the global runqueue) and heavily loaded machines (due to ++O(n) lookup) at this stage. Note that in terms of scalability, the number of ++_logical_ CPUs matters, not the number of _physical_ CPUs. Thus, a dual (2x) ++quad core (4X) hyperthreaded (2X) machine is effectively a 16X. Newer benchmark ++results are very promising indeed, without needing to tweak any knobs, features ++or options. Benchmark contributions are most welcome. ++ ++ ++Features ++ ++As the initial prime target audience for BFS was the average desktop user, it ++was designed to not need tweaking, tuning or have features set to obtain benefit ++from it. Thus the number of knobs and features has been kept to an absolute ++minimum and should not require extra user input for the vast majority of cases. ++There are precisely 2 tunables, and 2 extra scheduling policies. The rr_interval ++and iso_cpu tunables, and the SCHED_ISO and SCHED_IDLEPRIO policies. In addition ++to this, BFS also uses sub-tick accounting. What BFS does _not_ now feature is ++support for CGROUPS. The average user should neither need to know what these ++are, nor should they need to be using them to have good desktop behaviour. ++ ++rr_interval ++ ++There is only one "scheduler" tunable, the round robin interval. This can be ++accessed in ++ ++ /proc/sys/kernel/rr_interval ++ ++The value is in milliseconds, and the default value is set to 6 on a ++uniprocessor machine, and automatically set to a progressively higher value on ++multiprocessor machines. The reasoning behind increasing the value on more CPUs ++is that the effective latency is decreased by virtue of there being more CPUs on ++BFS (for reasons explained above), and increasing the value allows for less ++cache contention and more throughput. Valid values are from 1 to 1000 ++Decreasing the value will decrease latencies at the cost of decreasing ++throughput, while increasing it will improve throughput, but at the cost of ++worsening latencies. The accuracy of the rr interval is limited by HZ resolution ++of the kernel configuration. Thus, the worst case latencies are usually slightly ++higher than this actual value. The default value of 6 is not an arbitrary one. ++It is based on the fact that humans can detect jitter at approximately 7ms, so ++aiming for much lower latencies is pointless under most circumstances. It is ++worth noting this fact when comparing the latency performance of BFS to other ++schedulers. Worst case latencies being higher than 7ms are far worse than ++average latencies not being in the microsecond range. ++ ++Isochronous scheduling. ++ ++Isochronous scheduling is a unique scheduling policy designed to provide ++near-real-time performance to unprivileged (ie non-root) users without the ++ability to starve the machine indefinitely. Isochronous tasks (which means ++"same time") are set using, for example, the schedtool application like so: ++ ++ schedtool -I -e amarok ++ ++This will start the audio application "amarok" as SCHED_ISO. How SCHED_ISO works ++is that it has a priority level between true realtime tasks and SCHED_NORMAL ++which would allow them to preempt all normal tasks, in a SCHED_RR fashion (ie, ++if multiple SCHED_ISO tasks are running, they purely round robin at rr_interval ++rate). However if ISO tasks run for more than a tunable finite amount of time, ++they are then demoted back to SCHED_NORMAL scheduling. This finite amount of ++time is the percentage of _total CPU_ available across the machine, configurable ++as a percentage in the following "resource handling" tunable (as opposed to a ++scheduler tunable): ++ ++ /proc/sys/kernel/iso_cpu ++ ++and is set to 70% by default. It is calculated over a rolling 5 second average ++Because it is the total CPU available, it means that on a multi CPU machine, it ++is possible to have an ISO task running as realtime scheduling indefinitely on ++just one CPU, as the other CPUs will be available. Setting this to 100 is the ++equivalent of giving all users SCHED_RR access and setting it to 0 removes the ++ability to run any pseudo-realtime tasks. ++ ++A feature of BFS is that it detects when an application tries to obtain a ++realtime policy (SCHED_RR or SCHED_FIFO) and the caller does not have the ++appropriate privileges to use those policies. When it detects this, it will ++give the task SCHED_ISO policy instead. Thus it is transparent to the user. ++Because some applications constantly set their policy as well as their nice ++level, there is potential for them to undo the override specified by the user ++on the command line of setting the policy to SCHED_ISO. To counter this, once ++a task has been set to SCHED_ISO policy, it needs superuser privileges to set ++it back to SCHED_NORMAL. This will ensure the task remains ISO and all child ++processes and threads will also inherit the ISO policy. ++ ++Idleprio scheduling. ++ ++Idleprio scheduling is a scheduling policy designed to give out CPU to a task ++_only_ when the CPU would be otherwise idle. The idea behind this is to allow ++ultra low priority tasks to be run in the background that have virtually no ++effect on the foreground tasks. This is ideally suited to distributed computing ++clients (like setiathome, folding, mprime etc) but can also be used to start ++a video encode or so on without any slowdown of other tasks. To avoid this ++policy from grabbing shared resources and holding them indefinitely, if it ++detects a state where the task is waiting on I/O, the machine is about to ++suspend to ram and so on, it will transiently schedule them as SCHED_NORMAL. As ++per the Isochronous task management, once a task has been scheduled as IDLEPRIO, ++it cannot be put back to SCHED_NORMAL without superuser privileges. Tasks can ++be set to start as SCHED_IDLEPRIO with the schedtool command like so: ++ ++ schedtool -D -e ./mprime ++ ++Subtick accounting. ++ ++It is surprisingly difficult to get accurate CPU accounting, and in many cases, ++the accounting is done by simply determining what is happening at the precise ++moment a timer tick fires off. This becomes increasingly inaccurate as the ++timer tick frequency (HZ) is lowered. It is possible to create an application ++which uses almost 100% CPU, yet by being descheduled at the right time, records ++zero CPU usage. While the main problem with this is that there are possible ++security implications, it is also difficult to determine how much CPU a task ++really does use. BFS tries to use the sub-tick accounting from the TSC clock, ++where possible, to determine real CPU usage. This is not entirely reliable, but ++is far more likely to produce accurate CPU usage data than the existing designs ++and will not show tasks as consuming no CPU usage when they actually are. Thus, ++the amount of CPU reported as being used by BFS will more accurately represent ++how much CPU the task itself is using (as is shown for example by the 'time' ++application), so the reported values may be quite different to other schedulers. ++Values reported as the 'load' are more prone to problems with this design, but ++per process values are closer to real usage. When comparing throughput of BFS ++to other designs, it is important to compare the actual completed work in terms ++of total wall clock time taken and total work done, rather than the reported ++"cpu usage". ++ ++ ++Con Kolivas Fri Aug 27 2010 +diff -Nur a/Documentation/scheduler/sched-MuQSS.txt b/Documentation/scheduler/sched-MuQSS.txt +--- a/Documentation/scheduler/sched-MuQSS.txt 1970-01-01 01:00:00.000000000 +0100 ++++ b/Documentation/scheduler/sched-MuQSS.txt 2019-07-07 09:17:41.241241144 +0100 +@@ -0,0 +1,373 @@ ++MuQSS - The Multiple Queue Skiplist Scheduler by Con Kolivas. ++ ++MuQSS is a per-cpu runqueue variant of the original BFS scheduler with ++one 8 level skiplist per runqueue, and fine grained locking for much more ++scalability. ++ ++ ++Goals. ++ ++The goal of the Multiple Queue Skiplist Scheduler, referred to as MuQSS from ++here on (pronounced mux) is to completely do away with the complex designs of ++the past for the cpu process scheduler and instead implement one that is very ++simple in basic design. The main focus of MuQSS is to achieve excellent desktop ++interactivity and responsiveness without heuristics and tuning knobs that are ++difficult to understand, impossible to model and predict the effect of, and when ++tuned to one workload cause massive detriment to another, while still being ++scalable to many CPUs and processes. ++ ++ ++Design summary. ++ ++MuQSS is best described as per-cpu multiple runqueue, O(log n) insertion, O(1) ++lookup, earliest effective virtual deadline first tickless design, loosely based ++on EEVDF (earliest eligible virtual deadline first) and my previous Staircase ++Deadline scheduler, and evolved from the single runqueue O(n) BFS scheduler. ++Each component shall be described in order to understand the significance of, ++and reasoning for it. ++ ++ ++Design reasoning. ++ ++In BFS, the use of a single runqueue across all CPUs meant that each CPU would ++need to scan the entire runqueue looking for the process with the earliest ++deadline and schedule that next, regardless of which CPU it originally came ++from. This made BFS deterministic with respect to latency and provided ++guaranteed latencies dependent on number of processes and CPUs. The single ++runqueue, however, meant that all CPUs would compete for the single lock ++protecting it, which would lead to increasing lock contention as the number of ++CPUs rose and appeared to limit scalability of common workloads beyond 16 ++logical CPUs. Additionally, the O(n) lookup of the runqueue list obviously ++increased overhead proportionate to the number of queued proecesses and led to ++cache thrashing while iterating over the linked list. ++ ++MuQSS is an evolution of BFS, designed to maintain the same scheduling ++decision mechanism and be virtually deterministic without relying on the ++constrained design of the single runqueue by splitting out the single runqueue ++to be per-CPU and use skiplists instead of linked lists. ++ ++The original reason for going back to a single runqueue design for BFS was that ++once multiple runqueues are introduced, per-CPU or otherwise, there will be ++complex interactions as each runqueue will be responsible for the scheduling ++latency and fairness of the tasks only on its own runqueue, and to achieve ++fairness and low latency across multiple CPUs, any advantage in throughput of ++having CPU local tasks causes other disadvantages. This is due to requiring a ++very complex balancing system to at best achieve some semblance of fairness ++across CPUs and can only maintain relatively low latency for tasks bound to the ++same CPUs, not across them. To increase said fairness and latency across CPUs, ++the advantage of local runqueue locking, which makes for better scalability, is ++lost due to having to grab multiple locks. ++ ++MuQSS works around the problems inherent in multiple runqueue designs by ++making its skip lists priority ordered and through novel use of lockless ++examination of each other runqueue it can decide if it should take the earliest ++deadline task from another runqueue for latency reasons, or for CPU balancing ++reasons. It still does not have a balancing system, choosing to allow the ++next task scheduling decision and task wakeup CPU choice to allow balancing to ++happen by virtue of its choices. ++ ++As a further evolution of the design, MuQSS normally configures sharing of ++runqueues in a logical fashion for when CPU resources are shared for improved ++latency and throughput. By default it shares runqueues and locks between ++multicore siblings. Optionally it can be configured to run with sharing of ++SMT siblings only, all SMP packages or no sharing at all. Additionally it can ++be selected at boot time. ++ ++ ++Design details. ++ ++Custom skip list implementation: ++ ++To avoid the overhead of building up and tearing down skip list structures, ++the variant used by MuQSS has a number of optimisations making it specific for ++its use case in the scheduler. It uses static arrays of 8 'levels' instead of ++building up and tearing down structures dynamically. This makes each runqueue ++only scale O(log N) up to 64k tasks. However as there is one runqueue per CPU ++it means that it scales O(log N) up to 64k x number of logical CPUs which is ++far beyond the realistic task limits each CPU could handle. By being 8 levels ++it also makes the array exactly one cacheline in size. Additionally, each ++skip list node is bidirectional making insertion and removal amortised O(1), ++being O(k) where k is 1-8. Uniquely, we are only ever interested in the very ++first entry in each list at all times with MuQSS, so there is never a need to ++do a search and thus look up is always O(1). In interactive mode, the queues ++will be searched beyond their first entry if the first task is not suitable ++for affinity or SMT nice reasons. ++ ++Task insertion: ++ ++MuQSS inserts tasks into a per CPU runqueue as an O(log N) insertion into ++a custom skip list as described above (based on the original design by William ++Pugh). Insertion is ordered in such a way that there is never a need to do a ++search by ordering tasks according to static priority primarily, and then ++virtual deadline at the time of insertion. ++ ++Niffies: ++ ++Niffies are a monotonic forward moving timer not unlike the "jiffies" but are ++of nanosecond resolution. Niffies are calculated per-runqueue from the high ++resolution TSC timers, and in order to maintain fairness are synchronised ++between CPUs whenever both runqueues are locked concurrently. ++ ++Virtual deadline: ++ ++The key to achieving low latency, scheduling fairness, and "nice level" ++distribution in MuQSS is entirely in the virtual deadline mechanism. The one ++tunable in MuQSS is the rr_interval, or "round robin interval".

Thus, even if the time actually ++passes the deadline of another task that is queued, it will not get CPU time ++unless the current running task deschedules, and the time "base" (niffies) is ++constantly moving. ++ ++Task lookup: ++ ++As tasks are already pre-ordered according to anticipated scheduling order in ++the skip lists, lookup for the next suitable task per-runqueue is always a ++matter of simply selecting the first task in the 0th level skip list entry. ++In order to maintain optimal latency and fairness across CPUs, MuQSS does a ++novel examination of every other runqueue in cache locality order, choosing the ++best task across all runqueues. This provides near-determinism of how long any ++task across the entire system may wait before receiving CPU time. The other ++runqueues are first examine lockless and then trylocked to minimise the ++potential lock contention if they are likely to have a suitable better task. ++Each other runqueue lock is only held for as long as it takes to examine the ++entry for suitability. In "interactive" mode, the default setting, MuQSS will ++look for the best deadline task across all CPUs, while in !interactive mode, ++it will only select a better deadline task from another CPU if it is more ++heavily laden than the current one. ++ ++Lookup is therefore O(k) where k is number of CPUs. ++ ++ ++Latency. ++ ++Through the use of virtual deadlines to govern the scheduling order of normal ++tasks, queue-to-activation latency per runqueue is guaranteed to be bound by ++the rr_interval tunable which is set to 6ms by default. This means that the ++longest a CPU bound task will wait for more CPU is proportional to the number ++of running tasks and in the common case of 0-2 running tasks per CPU, will be ++under the 7ms threshold for human perception of jitter. Additionally, as newly ++woken tasks will have an early deadline from their previous runtime, the very ++tasks that are usually latency sensitive will have the shortest interval for ++activation, usually preempting any existing CPU bound tasks. ++ ++Tickless expiry: ++ ++A feature of MuQSS is that it is not tied to the resolution of the chosen tick ++rate in Hz, instead depending entirely on the high resolution timers where ++possible for sub-millisecond accuracy on timeouts regarless of the underlying ++tick rate. This allows MuQSS to be run with the low overhead of low Hz rates ++such as 100 by default, benefiting from the improved throughput and lower ++power usage it provides. Another advantage of this approach is that in ++combination with the Full No HZ option, which disables ticks on running task ++CPUs instead of just idle CPUs, the tick can be disabled at all times ++regardless of how many tasks are running instead of being limited to just one ++running task. Note that this option is NOT recommended for regular desktop ++users. ++ ++ ++Scalability and balancing. ++ ++Unlike traditional approaches where balancing is a combination of CPU selection ++at task wakeup and intermittent balancing based on a vast array of rules set ++according to architecture, busyness calculations and special case management, ++MuQSS indirectly balances on the fly at task wakeup and next task selection. ++During initialisation, MuQSS creates a cache coherency ordered list of CPUs for ++each logical CPU and uses this to aid task/CPU selection when CPUs are busy. ++Additionally it selects any idle CPUs, if they are available, at any time over ++busy CPUs according to the following preference: ++ ++ * Same thread, idle or busy cache, idle or busy threads ++ * Other core, same cache, idle or busy cache, idle threads. ++ * Same node, other CPU, idle cache, idle threads. ++ * Same node, other CPU, busy cache, idle threads. ++ * Other core, same cache, busy threads. ++ * Same node, other CPU, busy threads. ++ * Other node, other CPU, idle cache, idle threads. ++ * Other node, other CPU, busy cache, idle threads. ++ * Other node, other CPU, busy threads. ++ ++Mux is therefore SMT, MC and Numa aware without the need for extra ++intermittent balancing to maintain CPUs busy and make the most of cache ++coherency. ++ ++ ++Features ++ ++As the initial prime target audience for MuQSS was the average desktop user, it ++was designed to not need tweaking, tuning or have features set to obtain benefit ++from it. Thus the number of knobs and features has been kept to an absolute ++minimum and should not require extra user input for the vast majority of cases. ++There are 3 optional tunables, and 2 extra scheduling policies. The rr_interval, ++interactive, and iso_cpu tunables, and the SCHED_ISO and SCHED_IDLEPRIO ++policies. In addition to this, MuQSS also uses sub-tick accounting. What MuQSS ++does _not_ now feature is support for CGROUPS. The average user should neither ++need to know what these are, nor should they need to be using them to have good ++desktop behaviour. However since some applications refuse to work without ++cgroups, one can enable them with MuQSS as a stub and the filesystem will be ++created which will allow the applications to work. ++ ++rr_interval: ++ ++ /proc/sys/kernel/rr_interval ++ ++The value is in milliseconds, and the default value is set to 6. Valid values ++are from 1 to 1000 Decreasing the value will decrease latencies at the cost of ++decreasing throughput, while increasing it will improve throughput, but at the ++cost of worsening latencies. It is based on the fact that humans can detect ++jitter at approximately 7ms, so aiming for much lower latencies is pointless ++under most circumstances. It is worth noting this fact when comparing the ++latency performance of MuQSS to other schedulers. Worst case latencies being ++higher than 7ms are far worse than average latencies not being in the ++microsecond range. ++ ++interactive: ++ ++ /proc/sys/kernel/interactive ++ ++The value is a simple boolean of 1 for on and 0 for off and is set to on by ++default. Disabling this will disable the near-determinism of MuQSS when ++selecting the next task by not examining all CPUs for the earliest deadline ++task, or which CPU to wake to, instead prioritising CPU balancing for improved ++throughput. Latency will still be bound by rr_interval, but on a per-CPU basis ++instead of across the whole system. ++ ++Runqueue sharing. ++ ++By default MuQSS chooses to share runqueue resources (specifically the skip ++list and locking) between multicore siblings. It is configurable at build time ++to select between None, SMT, MC and SMP, corresponding to no sharing, sharing ++only between simultaneous mulithreading siblings, multicore siblings, or ++symmetric multiprocessing physical packages. Additionally it can be se at ++bootime with the use of the rqshare parameter. The reason for configurability ++is that some architectures have CPUs with many multicore siblings (>= 16) ++where it may be detrimental to throughput to share runqueues and another ++sharing option may be desirable. Additionally, more sharing than usual can ++improve latency on a system-wide level at the expense of throughput if desired. ++ ++The options are: ++none, smt, mc, smp ++ ++eg: ++ rqshare=mc ++ ++Isochronous scheduling: ++ ++Isochronous scheduling is a unique scheduling policy designed to provide ++near-real-time performance to unprivileged (ie non-root) users without the ++ability to starve the machine indefinitely. Isochronous tasks (which means ++"same time") are set using, for example, the schedtool application like so: ++ ++ schedtool -I -e amarok ++ ++This will start the audio application "amarok" as SCHED_ISO. How SCHED_ISO works ++is that it has a priority level between true realtime tasks and SCHED_NORMAL ++which would allow them to preempt all normal tasks, in a SCHED_RR fashion (ie, ++if multiple SCHED_ISO tasks are running, they purely round robin at rr_interval ++rate). However if ISO tasks run for more than a tunable finite amount of time, ++they are then demoted back to SCHED_NORMAL scheduling. This finite amount of ++time is the percentage of CPU available per CPU, configurable as a percentage in ++the following "resource handling" tunable (as opposed to a scheduler tunable): ++ ++iso_cpu: ++ ++ /proc/sys/kernel/iso_cpu ++ ++and is set to 70% by default. It is calculated over a rolling 5 second average ++Because it is the total CPU available, it means that on a multi CPU machine, it ++is possible to have an ISO task running as realtime scheduling indefinitely on ++just one CPU, as the other CPUs will be available. Setting this to 100 is the ++equivalent of giving all users SCHED_RR access and setting it to 0 removes the ++ability to run any pseudo-realtime tasks. ++ ++A feature of MuQSS is that it detects when an application tries to obtain a ++realtime policy (SCHED_RR or SCHED_FIFO) and the caller does not have the ++appropriate privileges to use those policies. When it detects this, it will ++give the task SCHED_ISO policy instead. Thus it is transparent to the user. ++ ++ ++Idleprio scheduling: ++ ++Idleprio scheduling is a scheduling policy designed to give out CPU to a task ++_only_ when the CPU would be otherwise idle. The idea behind this is to allow ++ultra low priority tasks to be run in the background that have virtually no ++effect on the foreground tasks. This is ideally suited to distributed computing ++clients (like setiathome, folding, mprime etc) but can also be used to start a ++video encode or so on without any slowdown of other tasks. To avoid this policy ++from grabbing shared resources and holding them indefinitely, if it detects a ++state where the task is waiting on I/O, the machine is about to suspend to ram ++and so on, it will transiently schedule them as SCHED_NORMAL. Once a task has ++been scheduled as IDLEPRIO, it cannot be put back to SCHED_NORMAL without ++superuser privileges since it is effectively a lower scheduling policy. Tasks ++can be set to start as SCHED_IDLEPRIO with the schedtool command like so: ++ ++schedtool -D -e ./mprime ++ ++Subtick accounting: ++ ++It is surprisingly difficult to get accurate CPU accounting, and in many cases, ++the accounting is done by simply determining what is happening at the precise ++moment a timer tick fires off. This becomes increasingly inaccurate as the timer ++tick frequency (HZ) is lowered. It is possible to create an application which ++uses almost 100% CPU, yet by being descheduled at the right time, records zero ++CPU usage. While the main problem with this is that there are possible security ++implications, it is also difficult to determine how much CPU a task really does ++use. Mux uses sub-tick accounting from the TSC clock to determine real CPU ++usage. Thus, the amount of CPU reported as being used by MuQSS will more ++accurately represent how much CPU the task itself is using (as is shown for ++example by the 'time' application), so the reported values may be quite ++different to other schedulers. When comparing throughput of MuQSS to other ++designs, it is important to compare the actual completed work in terms of total ++wall clock time taken and total work done, rather than the reported "cpu usage". ++ ++Symmetric MultiThreading (SMT) aware nice: ++ ++SMT, a.k.a. hyperthreading, is a very common feature on modern CPUs. While the ++logical CPU count rises by adding thread units to each CPU core, allowing more ++than one task to be run simultaneously on the same core, the disadvantage of it ++is that the CPU power is shared between the tasks, not summating to the power ++of two CPUs. The practical upshot of this is that two tasks running on ++separate threads of the same core run significantly slower than if they had one ++core each to run on. While smart CPU selection allows each task to have a core ++to itself whenever available (as is done on MuQSS), it cannot offset the ++slowdown that occurs when the cores are all loaded and only a thread is left. ++Most of the time this is harmless as the CPU is effectively overloaded at this ++point and the extra thread is of benefit. However when running a niced task in ++the presence of an un-niced task (say nice 19 v nice 0), the nice task gets ++precisely the same amount of CPU power as the unniced one. MuQSS has an ++optional configuration feature known as SMT-NICE which selectively idles the ++secondary niced thread for a period proportional to the nice difference, ++allowing CPU distribution according to nice level to be maintained, at the ++expense of a small amount of extra overhead. If this is configured in on a ++machine without SMT threads, the overhead is minimal. ++ ++ ++Con Kolivas Sat, 29th October 2016 +diff -Nur a/Documentation/sysctl/kernel.txt b/Documentation/sysctl/kernel.txt +--- a/Documentation/sysctl/kernel.txt 2019-07-07 09:08:19.122347611 +0100 ++++ b/Documentation/sysctl/kernel.txt 2019-07-07 09:17:41.251241479 +0100 +@@ -41,6 +41,7 @@ + - hung_task_check_interval_secs + - hung_task_warnings + - hyperv_record_panic_msg ++- iso_cpu + - kexec_load_disabled + - kptr_restrict + - l2cr [ PPC only ] +@@ -77,6 +78,7 @@ + - randomize_va_space + - real-root-dev ==> Documentation/admin-guide/initrd.rst + - reboot-cmd [ SPARC only ] ++- rr_interval + - rtsig-max + - rtsig-nr + - sched_energy_aware +@@ -101,6 +103,7 @@ + - unknown_nmi_panic + - watchdog + - watchdog_thresh ++- yield_type + - version + + ============================================================== +@@ -439,6 +442,16 @@ + + ============================================================== + ++iso_cpu: (MuQSS CPU scheduler only). ++ ++This sets the percentage cpu that the unprivileged SCHED_ISO tasks can ++run effectively at realtime priority, averaged over a rolling five ++seconds over the -whole- system, meaning all cpus. ++ ++Set to 70 (percent) by default. ++ ++============================================================== ++ + l2cr: (PPC only) + + This flag controls the L2 cache of G3 processor boards.

It can be easily changed. ++ ++The insertion routine has been implemented so as to use the ++dirty hack described in the CACM paper: if a random level is ++generated that is more than the current maximum level, the ++current maximum level plus one is used instead. ++ ++Levels start at zero and go up to MaxLevel (which is equal to ++MaxNumberOfLevels-1). ++ ++The routines defined in this file are: ++ ++init: defines slnode ++ ++new_skiplist: returns a new, empty list ++ ++randomLevel: Returns a random level based on a u64 random seed passed to it. ++In MuQSS, the "niffy" time is used for this purpose. ++ ++insert(l,key, value): inserts the binding (key, value) into l. This operation ++occurs in O(log n) time. ++ ++delnode(slnode, l, node): deletes any binding of key from the l based on the ++actual node value. This operation occurs in O(k) time where k is the ++number of levels of the node in question (max 8). The original delete ++function occurred in O(log n) time and involved a search. ++ ++MuQSS Notes: In this implementation of skiplists, there are bidirectional ++next/prev pointers and the insert function returns a pointer to the actual ++node the value is stored. The key here is chosen by the scheduler so as to ++sort tasks according to the priority list requirements and is no longer used ++by the scheduler after insertion. The scheduler lookup, however, occurs in ++O(1) time because it is always the first item in the level 0 linked list. ++Since the task struct stores a copy of the node pointer upon skiplist_insert, ++it can also remove it much faster than the original implementation with the ++aid of prev<->next pointer manipulation and no searching. ++ ++*/ ++ ++#include ++#include ++ ++#define MaxNumberOfLevels 8 ++#define MaxLevel (MaxNumberOfLevels - 1) ++ ++void skiplist_init(skiplist_node *slnode) ++{ ++ int i;

Copyright (C) 2011-2012 Nai Xia ++ * ++ * This is an improvement upon KSM. Some basic data structures and routines ++ * are borrowed from ksm.c . ++ * ++ * Its new features: ++ * 1. Full system scan: ++ * It automatically scans all user processes' anonymous VMAs. Kernel-user ++ * interaction to submit a memory area to KSM is no longer needed. ++ * ++ * 2. Rich area detection: ++ * It automatically detects rich areas containing abundant duplicated ++ * pages based. Rich areas are given a full scan speed. Poor areas are ++ * sampled at a reasonable speed with very low CPU consumption. ++ * ++ * 3. Ultra Per-page scan speed improvement: ++ * A new hash algorithm is proposed. As a result, on a machine with ++ * Core(TM)2 Quad Q9300 CPU in 32-bit mode and 800MHZ DDR2 main memory, it ++ * can scan memory areas that does not contain duplicated pages at speed of ++ * 627MB/sec ~ 2445MB/sec and can merge duplicated areas at speed of ++ * 477MB/sec ~ 923MB/sec. ++ * ++ * 4. Thrashing area avoidance: ++ * Thrashing area(an VMA that has frequent Ksm page break-out) can be ++ * filtered out. My benchmark shows it's more efficient than KSM's per-page ++ * hash value based volatile page detection. ++ * ++ * ++ * 5. Misc changes upon KSM: ++ * * It has a fully x86-opitmized memcmp dedicated for 4-byte-aligned page ++ * comparison. It's much faster than default C version on x86. ++ * * rmap_item now has an struct *page member to loosely cache a ++ * address-->page mapping, which reduces too much time-costly ++ * follow_page(). ++ * * The VMA creation/exit procedures are hooked to let the Ultra KSM know. ++ * * try_to_merge_two_pages() now can revert a pte if it fails.

Thrashing area avoidance: ++ * Thrashing area(an VMA that has frequent Ksm page break-out) can be ++ * filtered out. My benchmark shows it's more efficient than KSM's per-page ++ * hash value based volatile page detection. ++ * ++ * ++ * 5. Misc changes upon KSM: ++ * * It has a fully x86-opitmized memcmp dedicated for 4-byte-aligned page ++ * comparison. It's much faster than default C version on x86. ++ * * rmap_item now has an struct *page member to loosely cache a ++ * address-->page mapping, which reduces too much time-costly ++ * follow_page(). ++ * * The VMA creation/exit procedures are hooked to let the Ultra KSM know. ++ * * try_to_merge_two_pages() now can revert a pte if it fails. No break_ ++ * ksm is needed for this case. ++ * ++ * 6. Full Zero Page consideration(contributed by Figo Zhang) ++ * Now uksmd consider full zero pages as special pages and merge them to an ++ * special unswappable uksm zero page. ++ */ ++ ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++ ++#include ++#include "internal.h" ++ ++#ifdef CONFIG_X86 ++#undef memcmp ++ ++#ifdef CONFIG_X86_32 ++#define memcmp memcmpx86_32 ++/* ++ * Compare 4-byte-aligned address s1 and s2, with length n ++ */ ++int memcmpx86_32(void *s1, void *s2, size_t n) ++{ ++ size_t num = n / 4;

Copyright (C) 2011-2012 Nai Xia -+ * -+ * This is an improvement upon KSM. Some basic data structures and routines -+ * are borrowed from ksm.c . -+ * -+ * Its new features: -+ * 1. Full system scan: -+ * It automatically scans all user processes' anonymous VMAs. Kernel-user -+ * interaction to submit a memory area to KSM is no longer needed. -+ * -+ * 2.

Copyright (C) 2011-2012 Nai Xia -+ * -+ * This is an improvement upon KSM. Some basic data structures and routines -+ * are borrowed from ksm.c . -+ * -+ * Its new features: -+ * 1. Full system scan: -+ * It automatically scans all user processes' anonymous VMAs. Kernel-user -+ * interaction to submit a memory area to KSM is no longer needed. -+ * -+ * 2. Rich area detection: -+ * It automatically detects rich areas containing abundant duplicated -+ * pages based. Rich areas are given a full scan speed. Poor areas are -+ * sampled at a reasonable speed with very low CPU consumption. -+ * -+ * 3. Ultra Per-page scan speed improvement: -+ * A new hash algorithm is proposed. As a result, on a machine with -+ * Core(TM)2 Quad Q9300 CPU in 32-bit mode and 800MHZ DDR2 main memory, it -+ * can scan memory areas that does not contain duplicated pages at speed of -+ * 627MB/sec ~ 2445MB/sec and can merge duplicated areas at speed of -+ * 477MB/sec ~ 923MB/sec. -+ * -+ * 4. Thrashing area avoidance: -+ * Thrashing area(an VMA that has frequent Ksm page break-out) can be -+ * filtered out. My benchmark shows it's more efficient than KSM's per-page -+ * hash value based volatile page detection. -+ * -+ * -+ * 5. Misc changes upon KSM: -+ * * It has a fully x86-opitmized memcmp dedicated for 4-byte-aligned page -+ * comparison. It's much faster than default C version on x86. -+ * * rmap_item now has an struct *page member to loosely cache a -+ * address-->page mapping, which reduces too much time-costly -+ * follow_page(). -+ * * The VMA creation/exit procedures are hooked to let the Ultra KSM know. -+ * * try_to_merge_two_pages() now can revert a pte if it fails. No break_ -+ * ksm is needed for this case. -+ * -+ * 6. Full Zero Page consideration(contributed by Figo Zhang) -+ * Now uksmd consider full zero pages as special pages and merge them to an -+ * special unswappable uksm zero page. -+ */ -+ -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+ -+#include -+#include "internal.h" -+ -+#ifdef CONFIG_X86 -+#undef memcmp -+ -+#ifdef CONFIG_X86_32 -+#define memcmp memcmpx86_32 -+/* -+ * Compare 4-byte-aligned address s1 and s2, with length n -+ */ -+int memcmpx86_32(void *s1, void *s2, size_t n) -+{ -+ size_t num = n / 4;

Each component ++shall be described in order to understand the significance of, and reasoning for ++it. The codebase when the first stable version was released was approximately ++9000 lines less code than the existing mainline linux kernel scheduler (in ++2.6.31). This does not even take into account the removal of documentation and ++the cgroups code that is not used. ++ ++Design reasoning. ++ ++The single runqueue refers to the queued but not running processes for the ++entire system, regardless of the number of CPUs. The reason for going back to ++a single runqueue design is that once multiple runqueues are introduced, ++per-CPU or otherwise, there will be complex interactions as each runqueue will ++be responsible for the scheduling latency and fairness of the tasks only on its ++own runqueue, and to achieve fairness and low latency across multiple CPUs, any ++advantage in throughput of having CPU local tasks causes other disadvantages. ++This is due to requiring a very complex balancing system to at best achieve some ++semblance of fairness across CPUs and can only maintain relatively low latency ++for tasks bound to the same CPUs, not across them. To increase said fairness ++and latency across CPUs, the advantage of local runqueue locking, which makes ++for better scalability, is lost due to having to grab multiple locks. ++ ++A significant feature of BFS is that all accounting is done purely based on CPU ++used and nowhere is sleep time used in any way to determine entitlement or ++interactivity. Interactivity "estimators" that use some kind of sleep/run ++algorithm are doomed to fail to detect all interactive tasks, and to falsely tag ++tasks that aren't interactive as being so. The reason for this is that it is ++close to impossible to determine that when a task is sleeping, whether it is ++doing it voluntarily, as in a userspace application waiting for input in the ++form of a mouse click or otherwise, or involuntarily, because it is waiting for ++another thread, process, I/O, kernel activity or whatever. Thus, such an ++estimator will introduce corner cases, and more heuristics will be required to ++cope with those corner cases, introducing more corner cases and failed ++interactivity detection and so on. Interactivity in BFS is built into the design ++by virtue of the fact that tasks that are waking up have not used up their quota ++of CPU time, and have earlier effective deadlines, thereby making it very likely ++they will preempt any CPU bound task of equivalent nice level. See below for ++more information on the virtual deadline mechanism. Even if they do not preempt ++a running task, because the rr interval is guaranteed to have a bound upper ++limit on how long a task will wait for, it will be scheduled within a timeframe ++that will not cause visible interface jitter. ++ ++ ++Design details. ++ ++Task insertion. ++ ++BFS inserts tasks into each relevant queue as an O(1) insertion into a double ++linked list. On insertion, *every* running queue is checked to see if the newly ++queued task can run on any idle queue, or preempt the lowest running task on the ++system. This is how the cross-CPU scheduling of BFS achieves significantly lower ++latency per extra CPU the system has. In this case the lookup is, in the worst ++case scenario, O(n) where n is the number of CPUs on the system. ++ ++Data protection. ++ ++BFS has one single lock protecting the process local data of every task in the ++global queue. Thus every insertion, removal and modification of task data in the ++global runqueue needs to grab the global lock. However, once a task is taken by ++a CPU, the CPU has its own local data copy of the running process' accounting ++information which only that CPU accesses and modifies (such as during a ++timer tick) thus allowing the accounting data to be updated lockless. Once a ++CPU has taken a task to run, it removes it from the global queue. Thus the ++global queue only ever has, at most, ++ ++ (number of tasks requesting cpu time) - (number of logical CPUs) + 1 ++ ++tasks in the global queue. This value is relevant for the time taken to look up ++tasks during scheduling. This will increase if many tasks with CPU affinity set ++in their policy to limit which CPUs they're allowed to run on if they outnumber ++the number of CPUs. The +1 is because when rescheduling a task, the CPU's ++currently running task is put back on the queue. Lookup will be described after ++the virtual deadline mechanism is explained. ++ ++Virtual deadline. ++ ++The key to achieving low latency, scheduling fairness, and "nice level" ++distribution in BFS is entirely in the virtual deadline mechanism. The one ++tunable in BFS is the rr_interval, or "round robin interval". This is the ++maximum time two SCHED_OTHER (or SCHED_NORMAL, the common scheduling policy) ++tasks of the same nice level will be running for, or looking at it the other ++way around, the longest duration two tasks of the same nice level will be ++delayed for. When a task requests cpu time, it is given a quota (time_slice) ++equal to the rr_interval and a virtual deadline. The virtual deadline is ++offset from the current time in jiffies by this equation: ++ ++ jiffies + (prio_ratio * rr_interval) ++ ++The prio_ratio is determined as a ratio compared to the baseline of nice -20 ++and increases by 10% per nice level. The deadline is a virtual one only in that ++no guarantee is placed that a task will actually be scheduled by this time, but ++it is used to compare which task should go next. There are three components to ++how a task is next chosen. First is time_slice expiration. If a task runs out ++of its time_slice, it is descheduled, the time_slice is refilled, and the ++deadline reset to that formula above. Second is sleep, where a task no longer ++is requesting CPU for whatever reason. The time_slice and deadline are _not_ ++adjusted in this case and are just carried over for when the task is next ++scheduled. Third is preemption, and that is when a newly waking task is deemed ++higher priority than a currently running task on any cpu by virtue of the fact ++that it has an earlier virtual deadline than the currently running task. The ++earlier deadline is the key to which task is next chosen for the first and ++second cases. Once a task is descheduled, it is put back on the queue, and an ++O(n) lookup of all queued-but-not-running tasks is done to determine which has ++the earliest deadline and that task is chosen to receive CPU next. ++ ++The CPU proportion of different nice tasks works out to be approximately the ++ ++ (prio_ratio difference)^2 ++ ++The reason it is squared is that a task's deadline does not change while it is ++running unless it runs out of time_slice. Thus, even if the time actually ++passes the deadline of another task that is queued, it will not get CPU time ++unless the current running task deschedules, and the time "base" (jiffies) is ++constantly moving. ++ ++Task lookup. ++ ++BFS has 103 priority queues. 100 of these are dedicated to the static priority ++of realtime tasks, and the remaining 3 are, in order of best to worst priority, ++SCHED_ISO (isochronous), SCHED_NORMAL, and SCHED_IDLEPRIO (idle priority ++scheduling). When a task of these priorities is queued, a bitmap of running ++priorities is set showing which of these priorities has tasks waiting for CPU ++time. When a CPU is made to reschedule, the lookup for the next task to get ++CPU time is performed in the following way: ++ ++First the bitmap is checked to see what static priority tasks are queued. If ++any realtime priorities are found, the corresponding queue is checked and the ++first task listed there is taken (provided CPU affinity is suitable) and lookup ++is complete. If the priority corresponds to a SCHED_ISO task, they are also ++taken in FIFO order (as they behave like SCHED_RR). If the priority corresponds ++to either SCHED_NORMAL or SCHED_IDLEPRIO, then the lookup becomes O(n). At this ++stage, every task in the runlist that corresponds to that priority is checked ++to see which has the earliest set deadline, and (provided it has suitable CPU ++affinity) it is taken off the runqueue and given the CPU. If a task has an ++expired deadline, it is taken and the rest of the lookup aborted (as they are ++chosen in FIFO order). ++ ++Thus, the lookup is O(n) in the worst case only, where n is as described ++earlier, as tasks may be chosen before the whole task list is looked over. ++ ++ ++Scalability. ++ ++The major limitations of BFS will be that of scalability, as the separate ++runqueue designs will have less lock contention as the number of CPUs rises. ++However they do not scale linearly even with separate runqueues as multiple ++runqueues will need to be locked concurrently on such designs to be able to ++achieve fair CPU balancing, to try and achieve some sort of nice-level fairness ++across CPUs, and to achieve low enough latency for tasks on a busy CPU when ++other CPUs would be more suited. BFS has the advantage that it requires no ++balancing algorithm whatsoever, as balancing occurs by proxy simply because ++all CPUs draw off the global runqueue, in priority and deadline order. Despite ++the fact that scalability is _not_ the prime concern of BFS, it both shows very ++good scalability to smaller numbers of CPUs and is likely a more scalable design ++at these numbers of CPUs. ++ ++It also has some very low overhead scalability features built into the design ++when it has been deemed their overhead is so marginal that they're worth adding. ++The first is the local copy of the running process' data to the CPU it's running ++on to allow that data to be updated lockless where possible. Then there is ++deference paid to the last CPU a task was running on, by trying that CPU first ++when looking for an idle CPU to use the next time it's scheduled. Finally there ++is the notion of cache locality beyond the last running CPU. The sched_domains ++information is used to determine the relative virtual "cache distance" that ++other CPUs have from the last CPU a task was running on. CPUs with shared ++caches, such as SMT siblings, or multicore CPUs with shared caches, are treated ++as cache local. CPUs without shared caches are treated as not cache local, and ++CPUs on different NUMA nodes are treated as very distant. This "relative cache ++distance" is used by modifying the virtual deadline value when doing lookups. ++Effectively, the deadline is unaltered between "cache local" CPUs, doubled for ++"cache distant" CPUs, and quadrupled for "very distant" CPUs. The reasoning ++behind the doubling of deadlines is as follows. The real cost of migrating a ++task from one CPU to another is entirely dependant on the cache footprint of ++the task, how cache intensive the task is, how long it's been running on that ++CPU to take up the bulk of its cache, how big the CPU cache is, how fast and ++how layered the CPU cache is, how fast a context switch is... and so on. In ++other words, it's close to random in the real world where we do more than just ++one sole workload. The only thing we can be sure of is that it's not free. So ++BFS uses the principle that an idle CPU is a wasted CPU and utilising idle CPUs ++is more important than cache locality, and cache locality only plays a part ++after that. Doubling the effective deadline is based on the premise that the ++"cache local" CPUs will tend to work on the same tasks up to double the number ++of cache local CPUs, and once the workload is beyond that amount, it is likely ++that none of the tasks are cache warm anywhere anyway. The quadrupling for NUMA ++is a value I pulled out of my arse. ++ ++When choosing an idle CPU for a waking task, the cache locality is determined ++according to where the task last ran and then idle CPUs are ranked from best ++to worst to choose the most suitable idle CPU based on cache locality, NUMA ++node locality and hyperthread sibling business. They are chosen in the ++following preference (if idle): ++ ++* Same core, idle or busy cache, idle threads ++* Other core, same cache, idle or busy cache, idle threads. ++* Same node, other CPU, idle cache, idle threads. ++* Same node, other CPU, busy cache, idle threads. ++* Same core, busy threads. ++* Other core, same cache, busy threads. ++* Same node, other CPU, busy threads. ++* Other node, other CPU, idle cache, idle threads. ++* Other node, other CPU, busy cache, idle threads. ++* Other node, other CPU, busy threads. ++ ++This shows the SMT or "hyperthread" awareness in the design as well which will ++choose a real idle core first before a logical SMT sibling which already has ++tasks on the physical CPU. ++ ++Early benchmarking of BFS suggested scalability dropped off at the 16 CPU mark. ++However this benchmarking was performed on an earlier design that was far less ++scalable than the current one so it's hard to know how scalable it is in terms ++of both CPUs (due to the global runqueue) and heavily loaded machines (due to ++O(n) lookup) at this stage. Note that in terms of scalability, the number of ++_logical_ CPUs matters, not the number of _physical_ CPUs. Thus, a dual (2x) ++quad core (4X) hyperthreaded (2X) machine is effectively a 16X. Newer benchmark ++results are very promising indeed, without needing to tweak any knobs, features ++or options. Benchmark contributions are most welcome. ++ ++ ++Features ++ ++As the initial prime target audience for BFS was the average desktop user, it ++was designed to not need tweaking, tuning or have features set to obtain benefit ++from it. Thus the number of knobs and features has been kept to an absolute ++minimum and should not require extra user input for the vast majority of cases. ++There are precisely 2 tunables, and 2 extra scheduling policies. The rr_interval ++and iso_cpu tunables, and the SCHED_ISO and SCHED_IDLEPRIO policies. In addition ++to this, BFS also uses sub-tick accounting. What BFS does _not_ now feature is ++support for CGROUPS. The average user should neither need to know what these ++are, nor should they need to be using them to have good desktop behaviour. ++ ++rr_interval ++ ++There is only one "scheduler" tunable, the round robin interval. This can be ++accessed in ++ ++ /proc/sys/kernel/rr_interval ++ ++The value is in milliseconds, and the default value is set to 6 on a ++uniprocessor machine, and automatically set to a progressively higher value on ++multiprocessor machines. The reasoning behind increasing the value on more CPUs ++is that the effective latency is decreased by virtue of there being more CPUs on ++BFS (for reasons explained above), and increasing the value allows for less ++cache contention and more throughput. Valid values are from 1 to 1000 ++Decreasing the value will decrease latencies at the cost of decreasing ++throughput, while increasing it will improve throughput, but at the cost of ++worsening latencies. The accuracy of the rr interval is limited by HZ resolution ++of the kernel configuration. Thus, the worst case latencies are usually slightly ++higher than this actual value. The default value of 6 is not an arbitrary one. ++It is based on the fact that humans can detect jitter at approximately 7ms, so ++aiming for much lower latencies is pointless under most circumstances. It is ++worth noting this fact when comparing the latency performance of BFS to other ++schedulers. Worst case latencies being higher than 7ms are far worse than ++average latencies not being in the microsecond range. ++ ++Isochronous scheduling. ++ ++Isochronous scheduling is a unique scheduling policy designed to provide ++near-real-time performance to unprivileged (ie non-root) users without the ++ability to starve the machine indefinitely. Isochronous tasks (which means ++"same time") are set using, for example, the schedtool application like so: ++ ++ schedtool -I -e amarok ++ ++This will start the audio application "amarok" as SCHED_ISO. How SCHED_ISO works ++is that it has a priority level between true realtime tasks and SCHED_NORMAL ++which would allow them to preempt all normal tasks, in a SCHED_RR fashion (ie, ++if multiple SCHED_ISO tasks are running, they purely round robin at rr_interval ++rate). However if ISO tasks run for more than a tunable finite amount of time, ++they are then demoted back to SCHED_NORMAL scheduling. This finite amount of ++time is the percentage of _total CPU_ available across the machine, configurable ++as a percentage in the following "resource handling" tunable (as opposed to a ++scheduler tunable): ++ ++ /proc/sys/kernel/iso_cpu ++ ++and is set to 70% by default. It is calculated over a rolling 5 second average ++Because it is the total CPU available, it means that on a multi CPU machine, it ++is possible to have an ISO task running as realtime scheduling indefinitely on ++just one CPU, as the other CPUs will be available. Setting this to 100 is the ++equivalent of giving all users SCHED_RR access and setting it to 0 removes the ++ability to run any pseudo-realtime tasks. ++ ++A feature of BFS is that it detects when an application tries to obtain a ++realtime policy (SCHED_RR or SCHED_FIFO) and the caller does not have the ++appropriate privileges to use those policies. When it detects this, it will ++give the task SCHED_ISO policy instead. Thus it is transparent to the user. ++Because some applications constantly set their policy as well as their nice ++level, there is potential for them to undo the override specified by the user ++on the command line of setting the policy to SCHED_ISO. To counter this, once ++a task has been set to SCHED_ISO policy, it needs superuser privileges to set ++it back to SCHED_NORMAL. This will ensure the task remains ISO and all child ++processes and threads will also inherit the ISO policy. ++ ++Idleprio scheduling. ++ ++Idleprio scheduling is a scheduling policy designed to give out CPU to a task ++_only_ when the CPU would be otherwise idle. The idea behind this is to allow ++ultra low priority tasks to be run in the background that have virtually no ++effect on the foreground tasks. This is ideally suited to distributed computing ++clients (like setiathome, folding, mprime etc) but can also be used to start ++a video encode or so on without any slowdown of other tasks. To avoid this ++policy from grabbing shared resources and holding them indefinitely, if it ++detects a state where the task is waiting on I/O, the machine is about to ++suspend to ram and so on, it will transiently schedule them as SCHED_NORMAL. As ++per the Isochronous task management, once a task has been scheduled as IDLEPRIO, ++it cannot be put back to SCHED_NORMAL without superuser privileges. Tasks can ++be set to start as SCHED_IDLEPRIO with the schedtool command like so: ++ ++ schedtool -D -e ./mprime ++ ++Subtick accounting. ++ ++It is surprisingly difficult to get accurate CPU accounting, and in many cases, ++the accounting is done by simply determining what is happening at the precise ++moment a timer tick fires off. This becomes increasingly inaccurate as the ++timer tick frequency (HZ) is lowered. It is possible to create an application ++which uses almost 100% CPU, yet by being descheduled at the right time, records ++zero CPU usage. While the main problem with this is that there are possible ++security implications, it is also difficult to determine how much CPU a task ++really does use. BFS tries to use the sub-tick accounting from the TSC clock, ++where possible, to determine real CPU usage. This is not entirely reliable, but ++is far more likely to produce accurate CPU usage data than the existing designs ++and will not show tasks as consuming no CPU usage when they actually are. Thus, ++the amount of CPU reported as being used by BFS will more accurately represent ++how much CPU the task itself is using (as is shown for example by the 'time' ++application), so the reported values may be quite different to other schedulers. ++Values reported as the 'load' are more prone to problems with this design, but ++per process values are closer to real usage. When comparing throughput of BFS ++to other designs, it is important to compare the actual completed work in terms ++of total wall clock time taken and total work done, rather than the reported ++"cpu usage". ++ ++ ++Con Kolivas Fri Aug 27 2010 +diff -Nur a/Documentation/scheduler/sched-MuQSS.txt b/Documentation/scheduler/sched-MuQSS.txt +--- a/Documentation/scheduler/sched-MuQSS.txt 1970-01-01 01:00:00.000000000 +0100 ++++ b/Documentation/scheduler/sched-MuQSS.txt 2019-07-07 09:17:41.241241144 +0100 +@@ -0,0 +1,373 @@ ++MuQSS - The Multiple Queue Skiplist Scheduler by Con Kolivas. ++ ++MuQSS is a per-cpu runqueue variant of the original BFS scheduler with ++one 8 level skiplist per runqueue, and fine grained locking for much more ++scalability. ++ ++ ++Goals. ++ ++The goal of the Multiple Queue Skiplist Scheduler, referred to as MuQSS from ++here on (pronounced mux) is to completely do away with the complex designs of ++the past for the cpu process scheduler and instead implement one that is very ++simple in basic design. The main focus of MuQSS is to achieve excellent desktop ++interactivity and responsiveness without heuristics and tuning knobs that are ++difficult to understand, impossible to model and predict the effect of, and when ++tuned to one workload cause massive detriment to another, while still being ++scalable to many CPUs and processes. ++ ++ ++Design summary. ++ ++MuQSS is best described as per-cpu multiple runqueue, O(log n) insertion, O(1) ++lookup, earliest effective virtual deadline first tickless design, loosely based ++on EEVDF (earliest eligible virtual deadline first) and my previous Staircase ++Deadline scheduler, and evolved from the single runqueue O(n) BFS scheduler. ++Each component shall be described in order to understand the significance of, ++and reasoning for it. ++ ++ ++Design reasoning. ++ ++In BFS, the use of a single runqueue across all CPUs meant that each CPU would ++need to scan the entire runqueue looking for the process with the earliest ++deadline and schedule that next, regardless of which CPU it originally came ++from. This made BFS deterministic with respect to latency and provided ++guaranteed latencies dependent on number of processes and CPUs. The single ++runqueue, however, meant that all CPUs would compete for the single lock ++protecting it, which would lead to increasing lock contention as the number of ++CPUs rose and appeared to limit scalability of common workloads beyond 16 ++logical CPUs. Additionally, the O(n) lookup of the runqueue list obviously ++increased overhead proportionate to the number of queued proecesses and led to ++cache thrashing while iterating over the linked list. ++ ++MuQSS is an evolution of BFS, designed to maintain the same scheduling ++decision mechanism and be virtually deterministic without relying on the ++constrained design of the single runqueue by splitting out the single runqueue ++to be per-CPU and use skiplists instead of linked lists. ++ ++The original reason for going back to a single runqueue design for BFS was that ++once multiple runqueues are introduced, per-CPU or otherwise, there will be ++complex interactions as each runqueue will be responsible for the scheduling ++latency and fairness of the tasks only on its own runqueue, and to achieve ++fairness and low latency across multiple CPUs, any advantage in throughput of ++having CPU local tasks causes other disadvantages. This is due to requiring a ++very complex balancing system to at best achieve some semblance of fairness ++across CPUs and can only maintain relatively low latency for tasks bound to the ++same CPUs, not across them. To increase said fairness and latency across CPUs, ++the advantage of local runqueue locking, which makes for better scalability, is ++lost due to having to grab multiple locks. ++ ++MuQSS works around the problems inherent in multiple runqueue designs by ++making its skip lists priority ordered and through novel use of lockless ++examination of each other runqueue it can decide if it should take the earliest ++deadline task from another runqueue for latency reasons, or for CPU balancing ++reasons. It still does not have a balancing system, choosing to allow the ++next task scheduling decision and task wakeup CPU choice to allow balancing to ++happen by virtue of its choices. ++ ++As a further evolution of the design, MuQSS normally configures sharing of ++runqueues in a logical fashion for when CPU resources are shared for improved ++latency and throughput. By default it shares runqueues and locks between ++multicore siblings. Optionally it can be configured to run with sharing of ++SMT siblings only, all SMP packages or no sharing at all. Additionally it can ++be selected at boot time. ++ ++ ++Design details. ++ ++Custom skip list implementation: ++ ++To avoid the overhead of building up and tearing down skip list structures, ++the variant used by MuQSS has a number of optimisations making it specific for ++its use case in the scheduler. It uses static arrays of 8 'levels' instead of ++building up and tearing down structures dynamically. This makes each runqueue ++only scale O(log N) up to 64k tasks. However as there is one runqueue per CPU ++it means that it scales O(log N) up to 64k x number of logical CPUs which is ++far beyond the realistic task limits each CPU could handle. By being 8 levels ++it also makes the array exactly one cacheline in size. Additionally, each ++skip list node is bidirectional making insertion and removal amortised O(1), ++being O(k) where k is 1-8. Uniquely, we are only ever interested in the very ++first entry in each list at all times with MuQSS, so there is never a need to ++do a search and thus look up is always O(1). In interactive mode, the queues ++will be searched beyond their first entry if the first task is not suitable ++for affinity or SMT nice reasons. ++ ++Task insertion: ++ ++MuQSS inserts tasks into a per CPU runqueue as an O(log N) insertion into ++a custom skip list as described above (based on the original design by William ++Pugh). Insertion is ordered in such a way that there is never a need to do a ++search by ordering tasks according to static priority primarily, and then ++virtual deadline at the time of insertion. ++ ++Niffies: ++ ++Niffies are a monotonic forward moving timer not unlike the "jiffies" but are ++of nanosecond resolution. Niffies are calculated per-runqueue from the high ++resolution TSC timers, and in order to maintain fairness are synchronised ++between CPUs whenever both runqueues are locked concurrently. ++ ++Virtual deadline: ++ ++The key to achieving low latency, scheduling fairness, and "nice level" ++distribution in MuQSS is entirely in the virtual deadline mechanism. The one ++tunable in MuQSS is the rr_interval, or "round robin interval". This is the ++maximum time two SCHED_OTHER (or SCHED_NORMAL, the common scheduling policy) ++tasks of the same nice level will be running for, or looking at it the other ++way around, the longest duration two tasks of the same nice level will be ++delayed for. When a task requests cpu time, it is given a quota (time_slice) ++equal to the rr_interval and a virtual deadline. The virtual deadline is ++offset from the current time in niffies by this equation: ++ ++ niffies + (prio_ratio * rr_interval) ++ ++The prio_ratio is determined as a ratio compared to the baseline of nice -20 ++and increases by 10% per nice level. The deadline is a virtual one only in that ++no guarantee is placed that a task will actually be scheduled by this time, but ++it is used to compare which task should go next. There are three components to ++how a task is next chosen. First is time_slice expiration. If a task runs out ++of its time_slice, it is descheduled, the time_slice is refilled, and the ++deadline reset to that formula above. Second is sleep, where a task no longer ++is requesting CPU for whatever reason. The time_slice and deadline are _not_ ++adjusted in this case and are just carried over for when the task is next ++scheduled. Third is preemption, and that is when a newly waking task is deemed ++higher priority than a currently running task on any cpu by virtue of the fact ++that it has an earlier virtual deadline than the currently running task. The ++earlier deadline is the key to which task is next chosen for the first and ++second cases. ++ ++The CPU proportion of different nice tasks works out to be approximately the ++ ++ (prio_ratio difference)^2 ++ ++The reason it is squared is that a task's deadline does not change while it is ++running unless it runs out of time_slice. Thus, even if the time actually ++passes the deadline of another task that is queued, it will not get CPU time ++unless the current running task deschedules, and the time "base" (niffies) is ++constantly moving. ++ ++Task lookup: ++ ++As tasks are already pre-ordered according to anticipated scheduling order in ++the skip lists, lookup for the next suitable task per-runqueue is always a ++matter of simply selecting the first task in the 0th level skip list entry. ++In order to maintain optimal latency and fairness across CPUs, MuQSS does a ++novel examination of every other runqueue in cache locality order, choosing the ++best task across all runqueues. This provides near-determinism of how long any ++task across the entire system may wait before receiving CPU time. The other ++runqueues are first examine lockless and then trylocked to minimise the ++potential lock contention if they are likely to have a suitable better task. ++Each other runqueue lock is only held for as long as it takes to examine the ++entry for suitability. In "interactive" mode, the default setting, MuQSS will ++look for the best deadline task across all CPUs, while in !interactive mode, ++it will only select a better deadline task from another CPU if it is more ++heavily laden than the current one. ++ ++Lookup is therefore O(k) where k is number of CPUs. ++ ++ ++Latency. ++ ++Through the use of virtual deadlines to govern the scheduling order of normal ++tasks, queue-to-activation latency per runqueue is guaranteed to be bound by ++the rr_interval tunable which is set to 6ms by default. This means that the ++longest a CPU bound task will wait for more CPU is proportional to the number ++of running tasks and in the common case of 0-2 running tasks per CPU, will be ++under the 7ms threshold for human perception of jitter. Additionally, as newly ++woken tasks will have an early deadline from their previous runtime, the very ++tasks that are usually latency sensitive will have the shortest interval for ++activation, usually preempting any existing CPU bound tasks. ++ ++Tickless expiry: ++ ++A feature of MuQSS is that it is not tied to the resolution of the chosen tick ++rate in Hz, instead depending entirely on the high resolution timers where ++possible for sub-millisecond accuracy on timeouts regarless of the underlying ++tick rate. This allows MuQSS to be run with the low overhead of low Hz rates ++such as 100 by default, benefiting from the improved throughput and lower ++power usage it provides. Another advantage of this approach is that in ++combination with the Full No HZ option, which disables ticks on running task ++CPUs instead of just idle CPUs, the tick can be disabled at all times ++regardless of how many tasks are running instead of being limited to just one ++running task. Note that this option is NOT recommended for regular desktop ++users. ++ ++ ++Scalability and balancing. ++ ++Unlike traditional approaches where balancing is a combination of CPU selection ++at task wakeup and intermittent balancing based on a vast array of rules set ++according to architecture, busyness calculations and special case management, ++MuQSS indirectly balances on the fly at task wakeup and next task selection. ++During initialisation, MuQSS creates a cache coherency ordered list of CPUs for ++each logical CPU and uses this to aid task/CPU selection when CPUs are busy. ++Additionally it selects any idle CPUs, if they are available, at any time over ++busy CPUs according to the following preference: ++ ++ * Same thread, idle or busy cache, idle or busy threads ++ * Other core, same cache, idle or busy cache, idle threads. ++ * Same node, other CPU, idle cache, idle threads. ++ * Same node, other CPU, busy cache, idle threads. ++ * Other core, same cache, busy threads. ++ * Same node, other CPU, busy threads. ++ * Other node, other CPU, idle cache, idle threads. ++ * Other node, other CPU, busy cache, idle threads. ++ * Other node, other CPU, busy threads. ++ ++Mux is therefore SMT, MC and Numa aware without the need for extra ++intermittent balancing to maintain CPUs busy and make the most of cache ++coherency. ++ ++ ++Features ++ ++As the initial prime target audience for MuQSS was the average desktop user, it ++was designed to not need tweaking, tuning or have features set to obtain benefit ++from it. Thus the number of knobs and features has been kept to an absolute ++minimum and should not require extra user input for the vast majority of cases. ++There are 3 optional tunables, and 2 extra scheduling policies. The rr_interval, ++interactive, and iso_cpu tunables, and the SCHED_ISO and SCHED_IDLEPRIO ++policies. In addition to this, MuQSS also uses sub-tick accounting. What MuQSS ++does _not_ now feature is support for CGROUPS. The average user should neither ++need to know what these are, nor should they need to be using them to have good ++desktop behaviour. However since some applications refuse to work without ++cgroups, one can enable them with MuQSS as a stub and the filesystem will be ++created which will allow the applications to work. ++ ++rr_interval: ++ ++ /proc/sys/kernel/rr_interval ++ ++The value is in milliseconds, and the default value is set to 6. Valid values ++are from 1 to 1000 Decreasing the value will decrease latencies at the cost of ++decreasing throughput, while increasing it will improve throughput, but at the ++cost of worsening latencies. It is based on the fact that humans can detect ++jitter at approximately 7ms, so aiming for much lower latencies is pointless ++under most circumstances. It is worth noting this fact when comparing the ++latency performance of MuQSS to other schedulers. Worst case latencies being ++higher than 7ms are far worse than average latencies not being in the ++microsecond range. ++ ++interactive: ++ ++ /proc/sys/kernel/interactive ++ ++The value is a simple boolean of 1 for on and 0 for off and is set to on by ++default. Disabling this will disable the near-determinism of MuQSS when ++selecting the next task by not examining all CPUs for the earliest deadline ++task, or which CPU to wake to, instead prioritising CPU balancing for improved ++throughput. Latency will still be bound by rr_interval, but on a per-CPU basis ++instead of across the whole system. ++ ++Runqueue sharing. ++ ++By default MuQSS chooses to share runqueue resources (specifically the skip ++list and locking) between multicore siblings. It is configurable at build time ++to select between None, SMT, MC and SMP, corresponding to no sharing, sharing ++only between simultaneous mulithreading siblings, multicore siblings, or ++symmetric multiprocessing physical packages. Additionally it can be se at ++bootime with the use of the rqshare parameter. The reason for configurability ++is that some architectures have CPUs with many multicore siblings (>= 16) ++where it may be detrimental to throughput to share runqueues and another ++sharing option may be desirable. Additionally, more sharing than usual can ++improve latency on a system-wide level at the expense of throughput if desired. ++ ++The options are: ++none, smt, mc, smp ++ ++eg: ++ rqshare=mc ++ ++Isochronous scheduling: ++ ++Isochronous scheduling is a unique scheduling policy designed to provide ++near-real-time performance to unprivileged (ie non-root) users without the ++ability to starve the machine indefinitely. Isochronous tasks (which means ++"same time") are set using, for example, the schedtool application like so: ++ ++ schedtool -I -e amarok ++ ++This will start the audio application "amarok" as SCHED_ISO. How SCHED_ISO works ++is that it has a priority level between true realtime tasks and SCHED_NORMAL ++which would allow them to preempt all normal tasks, in a SCHED_RR fashion (ie, ++if multiple SCHED_ISO tasks are running, they purely round robin at rr_interval ++rate). However if ISO tasks run for more than a tunable finite amount of time, ++they are then demoted back to SCHED_NORMAL scheduling. This finite amount of ++time is the percentage of CPU available per CPU, configurable as a percentage in ++the following "resource handling" tunable (as opposed to a scheduler tunable): ++ ++iso_cpu: ++ ++ /proc/sys/kernel/iso_cpu ++ ++and is set to 70% by default. It is calculated over a rolling 5 second average ++Because it is the total CPU available, it means that on a multi CPU machine, it ++is possible to have an ISO task running as realtime scheduling indefinitely on ++just one CPU, as the other CPUs will be available. Setting this to 100 is the ++equivalent of giving all users SCHED_RR access and setting it to 0 removes the ++ability to run any pseudo-realtime tasks. ++ ++A feature of MuQSS is that it detects when an application tries to obtain a ++realtime policy (SCHED_RR or SCHED_FIFO) and the caller does not have the ++appropriate privileges to use those policies. When it detects this, it will ++give the task SCHED_ISO policy instead. Thus it is transparent to the user. ++ ++ ++Idleprio scheduling: ++ ++Idleprio scheduling is a scheduling policy designed to give out CPU to a task ++_only_ when the CPU would be otherwise idle. The idea behind this is to allow ++ultra low priority tasks to be run in the background that have virtually no ++effect on the foreground tasks. This is ideally suited to distributed computing ++clients (like setiathome, folding, mprime etc) but can also be used to start a ++video encode or so on without any slowdown of other tasks. To avoid this policy ++from grabbing shared resources and holding them indefinitely, if it detects a ++state where the task is waiting on I/O, the machine is about to suspend to ram ++and so on, it will transiently schedule them as SCHED_NORMAL. Once a task has ++been scheduled as IDLEPRIO, it cannot be put back to SCHED_NORMAL without ++superuser privileges since it is effectively a lower scheduling policy. Tasks ++can be set to start as SCHED_IDLEPRIO with the schedtool command like so: ++ ++schedtool -D -e ./mprime ++ ++Subtick accounting: ++ ++It is surprisingly difficult to get accurate CPU accounting, and in many cases, ++the accounting is done by simply determining what is happening at the precise ++moment a timer tick fires off. This becomes increasingly inaccurate as the timer ++tick frequency (HZ) is lowered. It is possible to create an application which ++uses almost 100% CPU, yet by being descheduled at the right time, records zero ++CPU usage. While the main problem with this is that there are possible security ++implications, it is also difficult to determine how much CPU a task really does ++use. Mux uses sub-tick accounting from the TSC clock to determine real CPU ++usage. Thus, the amount of CPU reported as being used by MuQSS will more ++accurately represent how much CPU the task itself is using (as is shown for ++example by the 'time' application), so the reported values may be quite ++different to other schedulers. When comparing throughput of MuQSS to other ++designs, it is important to compare the actual completed work in terms of total ++wall clock time taken and total work done, rather than the reported "cpu usage". ++ ++Symmetric MultiThreading (SMT) aware nice: ++ ++SMT, a.k.a. hyperthreading, is a very common feature on modern CPUs. While the ++logical CPU count rises by adding thread units to each CPU core, allowing more ++than one task to be run simultaneously on the same core, the disadvantage of it ++is that the CPU power is shared between the tasks, not summating to the power ++of two CPUs. The practical upshot of this is that two tasks running on ++separate threads of the same core run significantly slower than if they had one ++core each to run on. While smart CPU selection allows each task to have a core ++to itself whenever available (as is done on MuQSS), it cannot offset the ++slowdown that occurs when the cores are all loaded and only a thread is left. ++Most of the time this is harmless as the CPU is effectively overloaded at this ++point and the extra thread is of benefit. However when running a niced task in ++the presence of an un-niced task (say nice 19 v nice 0), the nice task gets ++precisely the same amount of CPU power as the unniced one. MuQSS has an ++optional configuration feature known as SMT-NICE which selectively idles the ++secondary niced thread for a period proportional to the nice difference, ++allowing CPU distribution according to nice level to be maintained, at the ++expense of a small amount of extra overhead. If this is configured in on a ++machine without SMT threads, the overhead is minimal. ++ ++ ++Con Kolivas Sat, 29th October 2016 +diff -Nur a/Documentation/sysctl/kernel.txt b/Documentation/sysctl/kernel.txt +--- a/Documentation/sysctl/kernel.txt 2019-07-07 09:08:19.122347611 +0100 ++++ b/Documentation/sysctl/kernel.txt 2019-07-07 09:17:41.251241479 +0100 +@@ -41,6 +41,7 @@ + - hung_task_check_interval_secs + - hung_task_warnings + - hyperv_record_panic_msg ++- iso_cpu + - kexec_load_disabled + - kptr_restrict + - l2cr [ PPC only ] +@@ -77,6 +78,7 @@ + - randomize_va_space + - real-root-dev ==> Documentation/admin-guide/initrd.rst + - reboot-cmd [ SPARC only ] ++- rr_interval + - rtsig-max + - rtsig-nr + - sched_energy_aware +@@ -101,6 +103,7 @@ + - unknown_nmi_panic + - watchdog + - watchdog_thresh ++- yield_type + - version + + ============================================================== +@@ -439,6 +442,16 @@ + + ============================================================== + ++iso_cpu: (MuQSS CPU scheduler only). ++ ++This sets the percentage cpu that the unprivileged SCHED_ISO tasks can ++run effectively at realtime priority, averaged over a rolling five ++seconds over the -whole- system, meaning all cpus. ++ ++Set to 70 (percent) by default. ++ ++============================================================== ++ + l2cr: (PPC only) + + This flag controls the L2 cache of G3 processor boards.

It can be easily changed. ++ ++The insertion routine has been implemented so as to use the ++dirty hack described in the CACM paper: if a random level is ++generated that is more than the current maximum level, the ++current maximum level plus one is used instead. ++ ++Levels start at zero and go up to MaxLevel (which is equal to ++MaxNumberOfLevels-1). ++ ++The routines defined in this file are: ++ ++init: defines slnode ++ ++new_skiplist: returns a new, empty list ++ ++randomLevel: Returns a random level based on a u64 random seed passed to it. ++In MuQSS, the "niffy" time is used for this purpose. ++ ++insert(l,key, value): inserts the binding (key, value) into l. This operation ++occurs in O(log n) time. ++ ++delnode(slnode, l, node): deletes any binding of key from the l based on the ++actual node value. This operation occurs in O(k) time where k is the ++number of levels of the node in question (max 8). The original delete ++function occurred in O(log n) time and involved a search. ++ ++MuQSS Notes: In this implementation of skiplists, there are bidirectional ++next/prev pointers and the insert function returns a pointer to the actual ++node the value is stored. The key here is chosen by the scheduler so as to ++sort tasks according to the priority list requirements and is no longer used ++by the scheduler after insertion. The scheduler lookup, however, occurs in ++O(1) time because it is always the first item in the level 0 linked list. ++Since the task struct stores a copy of the node pointer upon skiplist_insert, ++it can also remove it much faster than the original implementation with the ++aid of prev<->next pointer manipulation and no searching. ++ ++*/ ++ ++#include ++#include ++ ++#define MaxNumberOfLevels 8 ++#define MaxLevel (MaxNumberOfLevels - 1) ++ ++void skiplist_init(skiplist_node *slnode) ++{ ++ int i;

Copyright (C) 2011-2012 Nai Xia ++ * ++ * This is an improvement upon KSM. Some basic data structures and routines ++ * are borrowed from ksm.c . ++ * ++ * Its new features: ++ * 1. Full system scan: ++ * It automatically scans all user processes' anonymous VMAs. Kernel-user ++ * interaction to submit a memory area to KSM is no longer needed. ++ * ++ * 2. Rich area detection: ++ * It automatically detects rich areas containing abundant duplicated ++ * pages based. Rich areas are given a full scan speed. Poor areas are ++ * sampled at a reasonable speed with very low CPU consumption. ++ * ++ * 3. Ultra Per-page scan speed improvement: ++ * A new hash algorithm is proposed. As a result, on a machine with ++ * Core(TM)2 Quad Q9300 CPU in 32-bit mode and 800MHZ DDR2 main memory, it ++ * can scan memory areas that does not contain duplicated pages at speed of ++ * 627MB/sec ~ 2445MB/sec and can merge duplicated areas at speed of ++ * 477MB/sec ~ 923MB/sec. ++ * ++ * 4. Thrashing area avoidance: ++ * Thrashing area(an VMA that has frequent Ksm page break-out) can be ++ * filtered out. My benchmark shows it's more efficient than KSM's per-page ++ * hash value based volatile page detection. ++ * ++ * ++ * 5. Misc changes upon KSM: ++ * * It has a fully x86-opitmized memcmp dedicated for 4-byte-aligned page ++ * comparison. It's much faster than default C version on x86. ++ * * rmap_item now has an struct *page member to loosely cache a ++ * address-->page mapping, which reduces too much time-costly ++ * follow_page(). ++ * * The VMA creation/exit procedures are hooked to let the Ultra KSM know. ++ * * try_to_merge_two_pages() now can revert a pte if it fails.

Copyright (C) 2011-2012 Nai Xia ++ * ++ * This is an improvement upon KSM. Some basic data structures and routines ++ * are borrowed from ksm.c . ++ * ++ * Its new features: ++ * 1. Full system scan: ++ * It automatically scans all user processes' anonymous VMAs. Kernel-user ++ * interaction to submit a memory area to KSM is no longer needed. ++ * ++ * 2. Rich area detection: ++ * It automatically detects rich areas containing abundant duplicated ++ * pages based. Rich areas are given a full scan speed. Poor areas are ++ * sampled at a reasonable speed with very low CPU consumption. ++ * ++ * 3. Ultra Per-page scan speed improvement: ++ * A new hash algorithm is proposed. As a result, on a machine with ++ * Core(TM)2 Quad Q9300 CPU in 32-bit mode and 800MHZ DDR2 main memory, it ++ * can scan memory areas that does not contain duplicated pages at speed of ++ * 627MB/sec ~ 2445MB/sec and can merge duplicated areas at speed of ++ * 477MB/sec ~ 923MB/sec. ++ * ++ * 4. Thrashing area avoidance: ++ * Thrashing area(an VMA that has frequent Ksm page break-out) can be ++ * filtered out. My benchmark shows it's more efficient than KSM's per-page ++ * hash value based volatile page detection. ++ * ++ * ++ * 5. Misc changes upon KSM: ++ * * It has a fully x86-opitmized memcmp dedicated for 4-byte-aligned page ++ * comparison. It's much faster than default C version on x86. ++ * * rmap_item now has an struct *page member to loosely cache a ++ * address-->page mapping, which reduces too much time-costly ++ * follow_page(). ++ * * The VMA creation/exit procedures are hooked to let the Ultra KSM know. ++ * * try_to_merge_two_pages() now can revert a pte if it fails. No break_ ++ * ksm is needed for this case. ++ * ++ * 6. Full Zero Page consideration(contributed by Figo Zhang) ++ * Now uksmd consider full zero pages as special pages and merge them to an ++ * special unswappable uksm zero page. ++ */ ++ ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++ ++#include ++#include "internal.h" ++ ++#ifdef CONFIG_X86 ++#undef memcmp ++ ++#ifdef CONFIG_X86_32 ++#define memcmp memcmpx86_32 ++/* ++ * Compare 4-byte-aligned address s1 and s2, with length n ++ */ ++int memcmpx86_32(void *s1, void *s2, size_t n) ++{ ++ size_t num = n / 4;

Copyright (C) 2011-2012 Nai Xia -+ * -+ * This is an improvement upon KSM. Some basic data structures and routines -+ * are borrowed from ksm.c . -+ * -+ * Its new features: -+ * 1. Full system scan: -+ * It automatically scans all user processes' anonymous VMAs. Kernel-user -+ * interaction to submit a memory area to KSM is no longer needed. -+ * -+ * 2.

Copyright (C) 2011-2012 Nai Xia -+ * -+ * This is an improvement upon KSM. Some basic data structures and routines -+ * are borrowed from ksm.c . -+ * -+ * Its new features: -+ * 1. Full system scan: -+ * It automatically scans all user processes' anonymous VMAs. Kernel-user -+ * interaction to submit a memory area to KSM is no longer needed. -+ * -+ * 2. Rich area detection: -+ * It automatically detects rich areas containing abundant duplicated -+ * pages based. Rich areas are given a full scan speed. Poor areas are -+ * sampled at a reasonable speed with very low CPU consumption. -+ * -+ * 3. Ultra Per-page scan speed improvement: -+ * A new hash algorithm is proposed. As a result, on a machine with -+ * Core(TM)2 Quad Q9300 CPU in 32-bit mode and 800MHZ DDR2 main memory, it -+ * can scan memory areas that does not contain duplicated pages at speed of -+ * 627MB/sec ~ 2445MB/sec and can merge duplicated areas at speed of -+ * 477MB/sec ~ 923MB/sec. -+ * -+ * 4. Thrashing area avoidance: -+ * Thrashing area(an VMA that has frequent Ksm page break-out) can be -+ * filtered out. My benchmark shows it's more efficient than KSM's per-page -+ * hash value based volatile page detection. -+ * -+ * -+ * 5. Misc changes upon KSM: -+ * * It has a fully x86-opitmized memcmp dedicated for 4-byte-aligned page -+ * comparison. It's much faster than default C version on x86. -+ * * rmap_item now has an struct *page member to loosely cache a -+ * address-->page mapping, which reduces too much time-costly -+ * follow_page(). -+ * * The VMA creation/exit procedures are hooked to let the Ultra KSM know. -+ * * try_to_merge_two_pages() now can revert a pte if it fails. No break_ -+ * ksm is needed for this case. -+ * -+ * 6. Full Zero Page consideration(contributed by Figo Zhang) -+ * Now uksmd consider full zero pages as special pages and merge them to an -+ * special unswappable uksm zero page. -+ */ -+ -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+ -+#include -+#include "internal.h" -+ -+#ifdef CONFIG_X86 -+#undef memcmp -+ -+#ifdef CONFIG_X86_32 -+#define memcmp memcmpx86_32 -+/* -+ * Compare 4-byte-aligned address s1 and s2, with length n -+ */ -+int memcmpx86_32(void *s1, void *s2, size_t n) -+{ -+ size_t num = n / 4;
