Hardware locality, Hwloc, is a hardware-driven tool that provides command-line tools and uses the C API to obtain hierarchical critical computing elements in the system, including NUMA memory nodes, shared caching, processor sockets, processor cores, and processor threads. Hwloc also collects a variety of properties such as caching and memory information, as well as porting on a variety of different operating systems and platforms.
