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 <kernel@kolivas.org> 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 2019-01-05 20:22:51.089998199 +0000 -@@ -0,0 +1,347 @@ -+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. -+ -+ -+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.

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. -+ -+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 <kernel@kolivas.org> Sat, 29th October 2016 -diff -Nur a/Documentation/sysctl/kernel.txt b/Documentation/sysctl/kernel.txt ---- a/Documentation/sysctl/kernel.txt 2019-01-05 20:17:13.829237906 +0000 -+++ b/Documentation/sysctl/kernel.txt 2019-01-05 20:22:51.089998199 +0000 -@@ -39,6 +39,7 @@ - - hung_task_timeout_secs - - hung_task_warnings - - kexec_load_disabled -+- iso_cpu - - kptr_restrict - - l2cr [ PPC only ] - - modprobe ==> Documentation/debugging-modules.txt -@@ -73,6 +74,7 @@ - - randomize_va_space - - real-root-dev ==> Documentation/admin-guide/initrd.rst - - reboot-cmd [ SPARC only ] -+- rr_interval - - rtsig-max - - rtsig-nr - - seccomp/ ==> Documentation/userspace-api/seccomp_filter.rst -@@ -95,6 +97,7 @@ - - unknown_nmi_panic - - watchdog - - watchdog_thresh -+- yield_type - - version - - ============================================================== -@@ -397,6 +400,16 @@ - - ============================================================== - -+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.
