The Hardware Locality (hwloc) team is pleased to announce the first release candidates of v1.5.2, v1.4.3 and v1.3.3:
http://www.open-mpi.org/projects/hwloc/ The main reason for these releases is to fix a license issue. The GPL license of libpci/pciutils taints hwloc whenever you link with it (making hwloc *not BSD* anymore). We now use libpciaccess (from X.org) by default instead of libpci. See the Installation section in the documentation for details. People are encouraged to upgrade to hwloc v1.6.2 as soon as possible. If upgrading is not possible at the moment, these new releases will fix the above license issue in the meantime. Note that v1.3.3rc1 and v1.4.3rc1 *do not fix all known bugs* in their branch. Aside from including libpciaccess for the above issue, they only bring some minor changes that were already queued. Also we won't release the corresponding >indows builds because pciutils could not be used under Windows anyway. v1.5.2rc1 does fix all known bugs in the v1.5 series (and this one comes with a Windows build). The following is a summary of the changes since v1.5.1: * Use libpciaccess instead of pciutils/libpci by default for I/O discovery. pciutils/libpci is only used if --enable-libpci is given to configure because its GPL license may taint hwloc. See the Installation section in the documentation for details. * Fix get_cpubind on Solaris when bound to a single PU with processor_bind(). Thanks to Eugene Loh for reporting the problem and providing a patch. * Fix some DIR descriptor leaks on Linux. * Fix I/O device lists when some were filtered out after a XML import. * Add missing Backend string info on Solaris in most cases. * Fix the removal of I/O objects when importing a I/O-enabled XML topology without any I/O topology flag. * Fix the output of hwloc-calc -H --hierarchical when using logical indexes in the output. * Fix the pkg-config output with --libs --static. Thanks to Erik Schnetter for reporting one of the problems. -- Brice
