Abstraction of hardware architectures
hwloc 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 attributes such as cache and memory information. It primarily aims at helping high-performance computing applications with gathering information about the hardware so as to exploit it accordingly and efficiently.
hwloc may display the topology in multiple convenient formats. It also offers a powerful programming interface to gather information about the hardware, bind processes, and much more.
