(synopsis "Abstraction of hardware architectures")
(description
"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.")
;; But see above about linking against libpci.
