| PackageDescription | Hierarchical view of the machine - utilities
Hardware Locality (hwloc) provides a portable abstraction (across OS, versions,
architectures, ...) of the hierarchical topology of modern architectures. It
primarily aims at helping high-performance computing applications with
gathering information about the hardware so as to exploit it accordingly and
efficiently.
.
hwloc provides a hierarchical view of the machine, NUMA memory nodes,
sockets, shared caches, cores and simultaneous multithreading. It also gathers
various attributes such as cache and memory information.
.
hwloc supports old kernels not having sysfs topology information,
with knowledge of cpusets, offline cpus, and Kerrighed support
.
This package contains utilities to show the topology of the machine (lstopo and
hwloc-ls), manipulate cpu masks (hwloc-calc), and bind processes (hwloc-bind). |
