I think nothing actually uses what this feature provides but all headless machines suffer.

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.
