The usual reason for not doing this with UDP is that it turns a small amount of packet loss into lots more lossage. This is a real issue with ethernet when it drops packets when there is congestion. With IB the error rate is consistantly low. It could be that other HCAs don't like lots of UD messages in a row, either sending or receiving them efficiently. We never tried, as you can see the code is not written on top of verbs. -- greg _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
