cluster@gentoo.org Gentoo Cluster Project The Portable Hardware Locality (hwloc) software package provides a portable abstraction (across OS, versions, architectures, ...) of the hierarchical topology of modern architectures, including NUMA memory nodes, sockets, shared caches, cores and simultaneous multithreading. It also gathers various system attributes such as cache and memory information. It primarily aims at helping applications with gathering information about modern computing hardware so as to exploit it accordingly and efficiently. Enable the Cairo back-end of hwloc's lstopo command Enable the cpuid-based architecture specific support (x86 component) Enable CUDA device discovery using libcudart Enable GL display device discovery (NVCtrl) Add support for numa memory allocation Enable the NVML device discovery Enable PCI device discovery using libpci Build hwloc components as plugins so that the hwloc core library does not directly depend on their dependencies (for instance the libpci library) use libxml2 for XML support, instead of a custom minimalistic support use the X Window System
