Have you verified that you are running the same version of Open MPI on both
servers when launched from non-interactive logins?
This kind of error is somewhat typical if you accidentally mixed, for example,
Open MPI v1.6.x and v1.10.2 (i.e., v1.10.2 understands the --hnp-topo-sig back
end option, but v1.6.x does not).
