Subject: Re: Crafty 16.18 benchmarks on UltraSparc and Athlon

Go up one level in this thread


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.

Regards,

Djordje
