As a guy who's a big fan of low latency, I had to say that this is not a good generalization. Some apps become latency or message-rate sensitive if you scale to enough nodes at a fixed problem size. But most of the time, if you're running an app that is scaling really well on your network, it's neither bandwidth or latency bound. It's cpu bound. As another by the way (not directed at you, Jan), fat trees and Clos networks are not the same. -- greg _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
