I don't believe this is correct according to the IB spec -- modify QP is supposed to return an error only when the requested MTU is bigger than the MTUcap of the port. Even if we do have this patch, it seems there could still be trouble if an intermediate hop has a smaller MTU. Why is Open MPI trying to set a path MTU bigger than what the fabric actually supports? - R. _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
