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!
