The Hardware Locality (hwloc) team is pleased to announce the first
release candidate for v1.4:
http://www.open-mpi.org/projects/hwloc/
v1.4rc1 is the first milestone of a major feature release. The most
noticeable improvement is the ability to assemble the topologies of
multiple nodes into a single global one. See the Multi-node Topologies
section in the documentation for details.
Also please note that 64bits windows builds are now available for
download.
* Major features
+ Add "custom" interface and "assembler" tools to build multi-node
topology. See the Multi-node Topologies section in the documentation
for details.
* Interface improvements
+ Add symmetric_subtree object attribute to ease assumptions when consulting
regular symmetric topologies.
+ Add a CPUModel and CPUType info attribute to Socket objects on Linux
and Solaris.
+ Add hwloc_get_obj_index_inside_cpuset() to retrieve the "logical" index
of an object within a subtree of the topology.
+ Add more NVIDIA CUDA helpers in cuda.h and cudart.h to find hwloc objects
corresponding to CUDA devices.
* Discovery improvements
+ Add a group object above partial distance matrices to make sure
the matrices are available in the final topology, except when this
new object would contradict the existing hierarchy.
+ Grouping by distances now also works when loading from XML.
+ Fix some corner cases in object insertion, for instance when dealing
with NUMA nodes without any CPU.
* Backends
+ Implement hwloc_get_area_membind() on Linux.
+ Honor I/O topology flags when importing from XML.
+ Further improve XML-related error reporting.
+ Hide synthetic topology error messages unless HWLOC_SYNTHETIC_VERBOSE=1.
* Tools
+ Add synthetic exporting of symmetric topologies to lstopo.
+ lstopo --horiz and --vert can now be applied to some specific object types.
+ lstopo -v -p now displays distance matrices with physical indexes.
+ Add hwloc-distances utility to list distances.
* Documentation
+ Fix and/or document the behavior of most inline functions in hwloc/helper.h
when the topology contains some I/O or Misc objects.
+ Backend documentation enhancements.
