+ (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.")
