This needs testing but here is an initial suggestion for checking support for GPU enabled MPI in CRAY_MPICH this should enable direct inter GPU comms for a wider range of systems in the HPC space that don't always support OpenMPI for there scale out network.
Plan to test on MI210 nodes on ARCHER2 when they are available.
