Hmm... I'd like to find a way to avoid using the same QKey for everything, but maybe it's not any worse than what we have with IP anyway. I guess if we know if a UD QP will not join a multicast group, we can use any QKey, but use a well known QKey if it will join a multicast group. What would happen in the following situation: App 1: Creates QP with QKey=22 Joins multicast group 1 with QKey=33 App 2: Creates QP with QKey=44 Joins multicast group 1 Sends to multicast group but with QKey=22 - Sean _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
