I don't think it is a problem with the Opteron not being happy running in 32 bit mode. I see this no differently as when a regular Crafty revision is benchmarked on a Athlon MP system and gets poor speed-up. Once an AMD optimized revision (such as Aaron Gordon's) is benchmarked on the same machine, the scores will improve drastically. Mr. Richardson, would you like to try a profile guided optimized version of Crafty using the Intel C compiler? This has helped Athlon processors substantially with Crafty and I believe it could also help the Opteron. Contact Aaron Gordon at agordon@newageoc.com if interested. He's already agreed to help and will provide a binary and instructions upon request. -elc.
