The Hardware Locality (hwloc) team is pleased to announce the first release candidate for v1.8:
http://www.open-mpi.org/projects/hwloc/ v1.8rc1 is the first milestone of a major feature release. It adds PCI discovery on Linux without dependencies on external libs, a new API to manipulate differences between very similar topologies, multiple improvements to command-line tools, and more. * New components + Add the "linuxpci" component that always works on Linux even when libpciaccess and libpci aren't available (and even with a modified file-system root). By default the old "pci" component runs first because "linuxpci" lacks device names (obj->name is always NULL). * API + Add the topology difference API in hwloc/diff.h for manipulating many similar topologies. + Add hwloc_topology_dup() for duplicating an entire topology. + hwloc.h and hwloc/helper.h have been reorganized to clarify the documentation sections. The actual inline code has moved out of hwloc.h into the new hwloc/inlines.h. + Deprecated functions are now in hwloc/deprecated.h, and not in the official documentation anymore. * Tools + Add hwloc-diff and hwloc-patch tools together with the new diff API. + Add hwloc-compress-dir to (de)compress an entire directory of XML files using hwloc-diff and hwloc-patch. + Object colors in the graphical output of lstopo may be changed by adding a "lstopoStyle" info attribute. See CUSTOM COLORS in the lstopo(1) manpage for details. Thanks to Jirka Hladky for discussing the idea. + hwloc-gather-topology may now gather I/O-related files on Linux when --io is given. Only the linuxpci component supports discovering I/O objects from these extended tarballs. + hwloc-annotate now supports --ri to remove/replace info attributes with a given name. + hwloc-info supports "root" and "all" special locations for dumping information about the root object. + lstopo now supports --append-legend to append custom lines of text to the legend in the graphical output. Thanks to Jirka Hladky for discussing the idea. + hwloc-calc and friends have a more robust parsing of locations given on the command-line and they report useful error messages about it. + Add --whole-system to hwloc-bind, hwloc-calc, hwloc-distances and hwloc-distrib, and add --restrict to hwloc-bind for uniformity among tools. * Misc + Calling hwloc_topology_load() or hwloc_topology_set_*() on an already loaded topology now returns an error (deprecated since release 1.6.1). + Fix the initialisation of cpusets and nodesets in Group objects added when inserting PCI hostbridges. + Never merge Group objects that were added explicitly by the user with hwloc_custom_insert_group_object_by_parent(). + Add a sanity check during dynamic plugin loading to prevent some crashes when hwloc is dynamically loaded by another plugin mechanisms. + Add --with-hwloc-plugins-path to specify the install/load directories of plugins. + Add the MICSerialNumber info attribute to the root object when running hwloc inside a Xeon Phi to match the same attribute in the MIC OS device when running in the host. -- Brice
