Hi dann,
No i think he was talking about one cpu. The thread was from one of the
chessfun's test on single cpu. Crafty was doing well on a standard series
(probably 15 mins per game). But i didnt mean to point out Christophe alone, he
thought crafty might have a better utilization code. he thought, maybe he is not
sure himself ;). I was just curious about it and did a test. So what do you
think dann thus it prove that single cpu comp-comp matches are fair??
thanks
pavel
ps, i tried the single cpu test thingie you asked, no programs thus 100% all
thus their best, which is 99% :)
