Depending on how parralizable your process is, you might want to look into creating a cluster. You may be able to do it more cheaply. See http://acme.ecn.purdue.edu They did get lucky with part availability. Also for price / performance the AMD Duron beats the P3 easily. See www.cpuscorecard.com/cpu_latest.htm www.tomshardware.com/cpu/00q4/001017/athlon-09.html if that link doesn't work look for the cpu guide. or just search Tom's hardware for Duron. The FP performance kills the P3, while most other things are a little behind. You could create 2 or more boxes using Duron Chips and use them as a cluster. The one drawback is that as of august there were no chipsets for the Duron that could handle ECC memory. Don't know if that was a requirement for you. The ECC supporting chipsets were on the way supposedly. Hope that helps Tim On 23 Oct 2000, Allan Strand wrote: > Hi all, > > I have written a pretty complex simulation in c++.
