Except that in HPC, you're often talking to several neighbors. And even more neighbors if you have multiple cores per node. For example, if you have a 2D grid of nodes, and you have to exchange halos to the N S E W, then a node will talk to at least 4 neighbors (if you cleverly lay things out and combine messages), but more likely 12 neighbors, or maybe even 32. That's a lot more than 2 links. -- greg _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
