The Hardware Locality (hwloc) team is pleased to announce the release of v0.9.3:
  (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 v0.9.3 is a bug fix release. The following is a summary of changes as compared to v0.9.2:

* Fix to work with Autoconf 2.63.
* Fix various crashes in particular conditions:
  - xml files with root attributes
  - offline CPUs
  - partial sysfs support
  - unparseable /proc/cpuinfo
  - ignoring NUMA level while Misc level have been generated
* Tweak documentation a bit
* Do not require the pthread library for binding the current thread on Linux * Do not erroneously consider the sched_setaffinity prototype is the old version
  when there is actually none.
* Fix _syscall3 compilation on archs for which we do not have the
  sched_setaffinity system call number.
* Fix AIX binding.
* Fix libraries dependencies: now only lstopo depends on libtermcap, fix
  binutils-gold link
* Have make check always build and run hwloc-hello.c
* Do not limit size of a cpuset.

*** 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.*
