+ 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 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.
