+ """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."""
