FWIW: now that I am out of Intel, we are planning on upping the PMIx support
for GPUs in general, so I expect we'll be including this one. Support will
include providing info on capabilities (for both local and remote devices),
distances from every proc to each of its local GPUs, affinity settin

-- there's a bunch of explicit CUDA support.
But even some of that moved downward into both Libfabric and UCX and (at least
somewhat) out of OMPI.
That being said, we just added the AVX MPI_Op component -- equivalent
