Here is an interesting WAC run for the currently released version 16.18,
run on a 21264 alpha (667mhz, nothing top-secret):
0 20 40 60 80 100 120 140 160 180 200 220 240 260 280

The results are in order by column. positions 1-20 are in column 1, 21-40
are in column 2, etc. Max time limit was 60 seconds. This is the first run
I have done where it got all 300 correct on a single-cpu machine. If we drop
the time limit to 30 secs/position, it misses number 100 and 230, for a total
of 298. If we drop the time to 10 secs, same result. If we drop this to 5
secs, it drops to 297.
Obviously this box like crafty and vice-versa. :)
Here is the summary from the end of the test:
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
not bad, almost 800K on one cpu. Can you guess how the 1ghz and beyond
versions will run? And don't forget SMP as this is just one cpu. Pretty
amazing boxes, those alphas...
