The Hardware Locality (hwloc) team is pleased to announce the release of
v1.1.2rc1:
http://www.open-mpi.org/projects/hwloc/
This is the first release candidate for v1.1.2 which should be the last
bug fix release in the v1.1 serie. 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 v1.1.1:
* Fix a segfault in the distance-based grouping code when some objects
are not placed in any group. Thanks to Bernd Kallies for reporting
the problem and providing a patch.
* Fix the command-line parsing of hwloc-bind --mempolicy interleave.
Thanks to Guy Streeter for reporting the problem.
* Stop truncating the output in hwloc_obj_attr_snprintf() and in the
corresponding lstopo output. Thanks to Guy Streeter for reporting the
problem.
* Fix object levels ordering in synthetic topologies.
* Fix potential incoherency between device tree and kernel information,
when SMT is disabled on Power machines.
* Add some verbose error message reporting when it looks like the OS
gives erroneous information.
* Do not include unistd.h and stdint.h in public headers on Windows.
* Move config.h files into their own subdirectories to avoid name
conflicts when AC_CONFIG_HEADERS adds -I's for them.
* Remove the use of declaring variables inside "for" loops.
* Some other minor fixes.
* Many minor documentation fixes.
