I got together with Aaron this weekend, and we went through several different versions of Crafty to make the fastest possible SMP exe. Nothing was changed with the code, just compiler flags and optimizations. All were run on a Dual AMD 1.73Ghz. You will be able to get all the exe's on his site (http://speedycpu.dyndns.org/crafty) very soon. Crafty 18.15 from Hyatt's FTP: Crafty v18.15 (1 cpus) White(1): mt=2 max threads set to 2 White(1): bench Running benchmark. . . ......
