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’.
