Hello,

This series provides packages adding support for HPE’s Slingshot
high-speed interconnect to Open MPI.  I have tested the whole stack
with ‘intel-mpi-benchmarks’ on a Tier-1 supercomputer with a
Slingshot NIC (Adastra, in France) and confirmed that we get the
expected peak bandwidth, around 25 GB/s.

Libcxi and related packages were fully published as free software
just today.  I’m really happy about that because it unlocks access
to major supercomputers using a free software stack, and using Guix!
Incidentally, Guix will be the very first distro shipping packages
off their free releases.  :-)

Many thanks to the people we talked to at HPE who helped make this
happen faster.

Ludo’.

Ludovic Courtès (5):
  gnu: Add cassini-headers.
  gnu: Add cxi-driver.
  gnu: Add libcxi.
  gnu: libfabric: Enable libcxi support.
  gnu: openmpi: Disable static libraries.
