No disagreements here. >>Be that as it may, your supposition about feelings may be correct. However, the feelings were misdirected. Well it's just another feeling, but I suspect the organisers lean heavily towards favouring programs that have done well in SSDF [given SSDF people there] and Crafty has never challenged for the top. But isn't it misleading to look at SSDF results when SSDF doesn't use SMP machines? The reasoning seems to be , let's pick the top engines in SSDF, then exclude all except SMP capable engines. That would leave Fritz and Junior, Crafty is too "weak" and Shredder wasn't tested. The flaw of course is that SSDF doesn't test on duals or multiple CPUs? >>It is interesting, also that Vincent shows some sort of strange superlinear >>speedup.

True. Perhaps Crafty is just not good at Comp versus Comp games? Unlike Commercial programs, Crafty doesn't need to be designed to beat computers or top the SSDF list.. >I believe that Diep is going to lose. >I consider Crafty or Ferret as better programs. > Aaron
