I don't see how this could work-- to mimic IP, an app has to be able to multicast a datagram to multiple destination ports using the same multicast group. Since IB multicast groups have a Q_Key associated, the only way this could work is if all QPs and MCGs share one Q_Key. _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
