Charles -- It may have gotten lost in the middle of this thread, but the vendor-recommended way of running on InfiniBand these days is with UCX. I.e., install OpenUCX and use one of the UCX transports in Open MPI. Unless you have special requirements, you should likely give this a try and see if it works for you.
