hwloc (Hardware Locality) 1.11.13 is now available for download. https://www.open-mpi.org/software/hwloc/v1.11/
The most important change is support for upcoming Intel processors with multiple Dies per CPU. hwloc release 2.1 will add a new "Die" object. In the meantime 1.11.13 and 2.0.4 represent those Dies as "Die" groups. Summary of the changes since 1.11.12: * Add support for Linux 5.3 new sysfs cpu topology files with Die information. * Add support for Intel v2 Extended Topology Enumeration in the x86 backend. * Tiles, Modules and Dies are exposed as Groups for now. + HWLOC_DONT_MERGE_DIE_GROUPS=1 may be set in the environment to prevent Die groups from being automatically merged with identical parent or children. * Ignore NUMA node information from AMD topoext in the x86 backend, unless HWLOC_X86_TOPOEXT_NUMANODES=1 is set in the environment. * Group objects have a new "dont_merge" attribute to prevent them from being automatically merged with identical parent or children. All these changes are also in 2.0.4. I am considering stopping the 1.11.x branch in the near future. If you have a good reason not to upgrade to 2.x, or if you need help doing so, please tell us! -- Brice _______________________________________________ hwloc-announce mailing list hwloc-announce@lists.open-mpi.org https://lists.open-mpi.org/mailman/listinfo/hwloc-announce
