SemiconEng, on Athlon clusters from OSC
I found the story interesting in that we often think that everyone is getting the latest CPUs for their clusters. Obviously these recipients think that the best they can manage is a low-cost, hand-me-down, 32-bit system. Just think that a similar Opteron system, offering years more service lifetime and 64-bit capability, would probably cost less than $100,000. But they've bid to get these old processors because, I guess, they have no way to get a newer system. Lots of work will be spent on 32-bittedness that could be avoided by going to a newer architecture, but then again, that work will be done by graduate students...
BTW, as a Bee, I'd have thought you would have found what the replacement computer for the supercomputer center was. Think SGI.
