I get very interesting results for Crafty on my dual PII-400. With Crafty 16.17, the benchmark is extremely high: Total nodes: 108213432 Raw nodes per second: 578681 Total elapsed time: 187 SMP time-to-ply measurement: 3.422460 However, with Crafty 16.18, I get "only" about 431K of raw nodes per second. How come? And how does my 16.17 "off-the-shelf" Crafty produce about 578K of nodes? BTW, my experience on the ICS says that Crafty runs faster on the Intel chip than on the AMD chip.
