Don't you mean "when delivery is over a single subnet the error/drop packet rate is consistently low."? Over a long-haul connection is there any reason to expect that a large message would fare better than with UDP? Especially since the "cell size" would be smaller? _______________________________________________ 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
