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).
