IB experts, I'm playing around with UD QPs over IB, and using the librdma services to join and send to multicast groups. I can run seans mckey example program and it works. I've written a simply program to echo stdin to a mcast address and another program to read mcast packets and echo to stout. I run this on two hosts connected p2p via IB. And it works as expected.
However, if I run 2 instances of the app that reads mcasts and dumps them to stdout, I only get the mcast packets delivered to one of the applications. Namely the first one who joins the group seems to get the mcasts. I know for UDP/IP multicast, all applications bound to the same port and joined to the IP mcast addr will get a copy of incoming mcast packets. Is this not true for IB mcast? It appears not based on my tests... Thanks, Stevo. _______________________________________________ openib-general mailing list openib-general@openib.org http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
