> The Hardware Locality (hwloc) team is pleased to announce the release
> of v0.9.2 (we made some trivial documentation-only changes after the
> v0.9.1 tarballs were posted publicly, and have therefore re-released
> with the version "v0.9.2").
> (mirrors will update shortly)
> hwloc provides command line tools and a C API to obtain the
> hierarchical map of key computing elements, such as: NUMA memory
> nodes, shared caches, processor sockets, processor cores, and
> processor "threads". hwloc also gathers various attributes such as
> cache and memory information, and is portable across a variety of
> different operating systems and platforms.
> hwloc primarily aims at helping high-performance computing (HPC)
> applications, but is also applicable to any project seeking to exploit
> code and/or data locality on modern computing platforms.
> *** Note that the hwloc project represents the merger of the
> libtopology project from INRIA and the Portable Linux Processor
> Affinity (PLPA) sub-project from Open MPI. *Both of these prior
> projects are now deprecated.* The hwloc v0.9.1/v0.9.2 release is
> essentially a "re-branding" of the libtopology code base, but with
> both a few genuinely new features and a few PLPA-like features added
> in. More new features and more PLPA-like features will be added to
> hwloc over time.
> hwloc supports the following operating systems:
> * Linux (including old kernels not having sysfs topology
> information, with
> knowledge of cpusets, offline cpus, and Kerrighed support)
> * Solaris
> * AIX
> * Darwin / OS X
> * OSF/1 (a.k.a., Tru64)
> * HP-UX
> * Microsoft Windows
> hwloc only reports the number of processors on unsupported operating
> systems; no topology information is available.
> hwloc is available under the BSD license.
