Description:

The Portable Hardware Locality software package provides a portable
abstraction of the hierarchical topology of modern architectures,
including NUMA memory nodes, sockets, shared caches, cores and
simultaneous multi-threading. 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. Try out the command "lstopo" and enjoy the show.
