Sure. My intend was not to compare between IB and Quadrics, but to show that the network/host injection rate is very relevant in contention tests. For given host injection rate, increase in network capability reduces the contention (assuming finite number of hosts.....). As for the numbers: Send ave: IB SDR 263MB, Quadrics 369MB, IB DDR 453MB Receive ave: IB SDR 340MB, Quadrics 370MB, IB DDR 547MB I noticed that Quadrics decided to use just part of those numbers for their poster at ISC ... ;-) Gilad. _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
