hwloc (Hardware Locality) 2.9.0rc1 is now available for download.


v2.9.0 is a small release that publishes several improvements
and fixes from the last months.

We are working on a v3.0 releases that will slightly break the
API and ABI, remove support from obsolete hardware, etc.
v2.9.x (and maybe even a v2.10.x if necessary) will be maintained
in parallel to v3.0 development and first releases.

The following is a summary of the changes since v2.8.0.

Version 2.9.0
* Backends
  + Expose the memory size of CXL memory devices (Type 3) on Linux.
  + The LevelZero backend now reports the "XeLinkBandwidth" distance
    matrix between L0 devices (and subdevices) when available.
  + Add support for CUDA compute capability up to 9.0.
* Tools
  + lstopo now switches to console mode when its output is redirected.
    Graphical window mode may be forced back with --of window.
  + hwloc-calc now accepts "numa" in -H, and I/O subtypes such as "gpu"
    in -I and -N.
