Haddock, Re: I stand by what I said earlier, the new entries to the top500 list this year will be Opterons and Itaniums. Why bother with anything else?
I suspect we'll continue to see a lot of Xeons on the list. Why? They're cheap, the infrastructure is all there, and there is exceptionally broad OEM support. The enterprise market doesn't do a 180 degree turn now that AMD has 64-bit extensions.
