The current beta MS Win xp x64 edition is currently free and it not expire for one year. 64 bit Crafty runs 33% faster in 64 bit mode as compared to 32 bit Crafty on the same Opteron machine Opteron. By ther design , Opterons are much more efficient than Xeon chips per Ghz for Crafty . Xeons will run Crafty32 near 375Knps/Ghz Opterons will run Crafty32 near 750Knps/Ghz Opterons will run Crafty64 near 1000Knps/Ghz So a dual 846 Opteron (2.0 Ghz) will run Crafty near 4M nps. The command is "bench" to run the Crafty Benchmark ( at the command prompt). Let me know (via email) when have the 64 bit MS OS installed and I will send you Crafty 64 for Windows 64.
