Actually several of them did mention it, but I guess you (and they) haven't seen my talk where I show some real applications where the rate that you can send small messages is the dominant predictor of performance. e.g. InfiniPath is 2X lower ping-pong latency, but can get much better than 2X the performance on real applications, if they're streaming small messages. -- greg _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
