+The Portable Hardware Locality (hwloc) software package 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 system attributes such as cache and memory
+information as well as the locality of I/O devices such as network
+interfaces, InfiniBand HCAs or GPUs.
+
+hwloc primarily aims at helping applications with gathering information
+about increasingly complex parallel computing platforms so as to exploit
+them accordingly and efficiently. For instance, two tasks that tightly
+cooperate should probably be placed onto cores sharing a cache. However,
+two independent memory-intensive tasks should better be spread out onto
+different sockets so as to maximize their memory throughput. As
+described in this paper, OpenMP threads have to be placed according to
+their affinities and to the hardware characteristics. MPI
+implementations apply similar techniques while also adapting their
+communication strategies to the network locality as described in this
+paper or this one.
+
+hwloc may also help many applications just by providing a portable CPU
+and memory binding API and a reliable way to find out how many cores
+and/or hardware threads are available.
