I have been working both with Eugene and AMD. The following bench run is on a quad 1.8ghz opteron, 8 gigs of ram. The only "option" I have set is "mt=4". There is _no_ assembly code in this version, pure C only. I am looking at updating the asm to 64 bit but that will take some time and studying. Meanwhile: Crafty v19.6 (1 cpus) White(1): mt=4 max threads set to 4 White(1): bench Running benchmark. . . ...... Total nodes: 105863114 Raw nodes per second: 5881284 Total elapsed time: 18 SMP time-to-ply measurement: 35.555556 This is using gcc, although I am not sure whether it is producing 64 bit or 32 bit code at the moment. However, 5.8M nps is not bad. About 1M less than Eugene's MSVC numbers. I will look into the 64 bit stuff more to see if gcc is producing real opteron assembly or not... And I will study the PGO options although the list time I tried them on GCC the compiler promptly crashed. :) Note that the above is with default hash and everything, no endgame tables, no opening book, etc...
