I agree that there is some improvement in going from one QP per UDP socket to one per node, but it still will likely not scale to 10,000 node clusters, which is something that Oracle probably does not care about, but others in HPC do. If we are going to invent a Reliable Datagram Service, shouldn't it be made to scale so that MPIs that currently use datagrams could also benefit ? woody _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
