Can anyone report experience with recent OMPI on POWER (ppc64le) hardware, e.g. Summit? When I tried on similar nodes to Summit's (but fewer!), the IMB-RMA benchmark SEGVs early on. Before I try to debug it, I'd be interested to know if anyone else has investigated that or had better luck and, if so, how. See <https://github.com/open-mpi/ompi/issues/8102>
