Again, I claim to have actually _run_ and _tested_ on duals, 4-ways and 8-ways. I don't have to guess what happens. I already _know_. The dual opteron can be treated just like an SMP opteron and the program will do just fine. Certainly will not change the speedup by more than .1 or so to really optimize it for the NUMA issues. > >>Equal hardware SSDF shredder8-crafty : 43.5 - 3.5 > >I was going to look that up later, thanks! > >So we can expect in a 10 game match, nothing better than 9 - 1 from Crafty, >based on SSDF results. Interesting...
