Hi Sabu,
Could you try configure MPICH with `--with-device=ch4:ucx`?

Subject: [mpich-discuss] MPI over infiniband
Good day to all,
Question, we have been trying to use MPICH over infiniband fabric, but we can't seem to get it to work unless it is IPoIB. We have seen options in OpenMPI that automatically selects Infiniband as the first choice path, but I don't see anything similar for MPICH.
Looking forward to your input on this.
Thanks!
