Thanks Here is the output for running WAC at 60 seconds per move on a single xeon cpu, 700mhz, 1M L2 cache: test results summary: total positions searched.......... 300 number right...................... 299 number wrong...................... 1 percentage right.................. 99 percentage wrong.................. 0 total nodes searched.............. 132559227.0 average search depth.............. 4.7 nodes per second.................. 412161 Here is the same test run on a 21264 alpha at 600mhz: test results summary: total positions searched.......... 300 number right...................... 300 number wrong...................... 0 percentage right.................. 100 percentage wrong.................. 0 total nodes searched.............. 236973211.0 average search depth.............. 4.5 nodes per second.................. 783641 As you can see, the alpha has a 16% slower clock speed, but is nearly 2x faster...
