: There's another interesting paradigm out there. Consider clusters : of SMPs... Many problems break up into smaller ones that fit current : SMPs quite nicely. IBM's latest SP/2s are clump machines... The : Linux kernel scaling to 4 cpus could fit this beautifully on the right : systems.
I think this is worth repeating. When I was starting the clusters effort at Sun, it got cast as a "cluster-or-SMP" fight which was most unfortunate. You absolutely want to cluster SMPs - the SMP nodes provide you with a level of dynamic load balancing which is virtually impossible to get in a cluster of UP nodes.
Do not think of clusters as "clusters on UPs" only - the people who want the highest performance will be clustering the most scalable SMP machines they can find.
