The Portable Hardware Locality (hwloc) software package provides a portable abstraction (across OS, versions, architectures, ...) of the hierarchical topology of modern architectures, including as follows:

• NUMA memory nodes;
• sockets;
• shared caches;
• cores and simultaneous multithreading. It also gathers various system attributes such as cache and memory information as well as the locality of I/O devices (such as network interfaces, InfiniBand HCAs or GPUs). It primarily aims at helping applications with gathering information about modern computing hardware so as to exploit it accordingly and efficiently [1].
