longDescription = ''
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.
