On the G5 side of things so far I don't have as positive comments as in my earlier mail. We got 4 2Ghz dual G5s as soon as they were available and we really really felt like Apple's guinea pigs (though the price was not guinea pig price) as 3 out of 4 had various hardware issues, instabilities,etc. Once again, they were very prompt and helpful in sorting those issues out, but still for quite a while we weren't really productive on those machines. In a week or so we should be Sun Grid Engine'ing them together so we should know how well they behave under stress,etc. Elia > Arnie Miles > Advanced Research Computing > Georgetown University > > On Fri, 2004-03-05 at 10:53, Michael Chute wrote: >> For my two cents I would have to disagree with the Xeon approach.
