Portable Hardware Locality software package
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;
- 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 .
