Building A Homemade Chess Supercomputer

nado writes "There's a new article on Chessbase.com which has GM John Nunn showing you his chess-orientated PC upgrade to a double Xeon system, with some Fritz benchmarks." Elsewhere in the article, John Nunn discusses the unique computer needs for chess computation: "One of the problems with currently available processors is that they are not particularly well suited to the integer calculations used for chess. A Pentium 4 will be slower at chess than a Pentium 3 of an equivalent clock speed."

XP vs 2000 in the application (Hyperthreading)

[Akai]

I just turned up a dual Xeon 2.4 rack-mount server for work and it's BIOS mentioned warned us to turn off Hyperthreading for anything other than Windows XP or Linux 2.4 (yeah, mention of Linux in BIOS! :).

Anyways, since I am using linux 2.4, two hyperthreaded Xeons look like four processors to the box, I"m sure it's not the same performance of for seperate processors, but I'm hopeing it's at least slightly better then two non Xeons :)

The writer of the article wrote that for Windows he prefers 2000 over XP. I am curious if XP (or Linux 2.4) and thus Hyperthreading might help his already built computer with a bit more performance...
