Dann was kind enough to send me the exe he used to bench the P4 system. So I thought I would share. Dual 1.73 GHz AMD (1.59 SMP gain for 2 CPU's): C:\crafty>craftysmpi EPD Kit revision date: 1996.04.21 found computer opening book file [./bookc.bin]. book file disabled. hash table memory = 48M bytes. pawn hash table memory = 5M bytes. Crafty v18.9 (1 cpus) White(1): mt=2 max threads set to 2 White(1): bench Running benchmark. . . ......
