The Hardware Locality (hwloc) team is pleased to announce the release of v1.1.1:
http://www.open-mpi.org/projects/hwloc/ v1.1.1 is a minor bug fix release. All hwloc users are encouraged to upgrade when possible. 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. The following is a summary of the changes since v1.1: * Add hwloc_get_api_version() which returns the version of hwloc used at runtime. Thanks to Guy Streeter for the suggestion. * Fix the number of hugepages reported for NUMA nodes on Linux. * Fix hwloc_bitmap_to_ulong() right after allocating the bitmap. Thanks to Bernd Kallies for reporting the problem. * Fix hwloc_bitmap_from_ith_ulong() to properly zero the first ulong. Thanks to Guy Streeter for reporting the problem. * Fix hwloc_get_membind_nodeset() on Linux. Thanks to Bernd Kallies for reporting the problem and providing a patch. * Fix some file descriptor leaks in the Linux discovery. * Fix the minimum width of NUMA nodes, caches and the legend in the graphical lstopo output. Thanks to Jirka Hladky for reporting the problem. * Various fixes to bitmap conversion from/to taskset-strings. * Fix and document snprintf functions behavior when the buffer size is too small or zero. Thanks to Guy Streeter for reporting the problem. * Fix configure to avoid spurious enabling of the cpuid backend. Thanks to Tim Anderson for reporting the problem. * Cleanup error management in hwloc-gather-topology.sh. Thanks to Jirka Hladky for reporting the problem and providing a patch. * Add a manpage and usage for hwloc-gather-topology.sh on Linux. Thanks to Jirka Hladky for providing a patch. * Memory binding documentation enhancements. -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
