this pingpong example is somewhat of a special case, since we know in advance that no more than 1 send and 1 receive completion can ever be outstanding, so a single ibv_poll_cq suffices. (Although thinking about this now, there may be some theoretical races that could case problems) - R. _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
