Benchmarks for Crafty 16.18
---------------------------

167 MHz UltraSparc (Solaris 2.6, compiled with gcc 2.8.1)

Total nodes: 61096154
Raw nodes per second: 69035
Total elapsed time: 885
SMP time-to-ply measurement: 0.723164

250 MHz UltraSparc (Solaris 2.7, compiled with gcc 2.8.1)

Total nodes: 61096154
Raw nodes per second: 95612
Total elapsed time: 639
SMP time-to-ply measurement: 1.001565

600 MHz Athlon (wcrafty-16.18.exe from Bob's ftp site)

Total nodes: 68509284
Raw nodes per second: 422896
Total elapsed time: 162
SMP time-to-ply measurement: 3.950617

Notes:
I'm very pleased with my new AMD Athlon 600MHz - that looks like
a pretty good benchmark for Crafty to me. Totally vanilla settings, just
downloaded the exe file and double-clicked on it, worked like a dream. Next stop
Winboard!

I've also included bechmarks from the machines at work, this is a compile of my
own (I hope we'll get gcc2.95 soon and speed things up), as Bob says, these
machines don't see to perform well MHz for MHz and I know they were expensive.

Judging by these numbers it would need a 1000MHz UltraSparc to perform as well
as my 600MHz Athlon.
