I recently checked so-called public relase 3 (essentially the same as the initial release, right?) as well and its 4 core version shows over 330% in top command. So, I believe the big version doesn't have the same parallelism. Does MoGo use simple mutex or some smarter locks? I'd like to run newer version on cgos anyway :) Hideki >_______________________________________________ >computer-go mailing list >computer-go@computer-go.org >http://www.computer-go.org/mailman/listinfo/computer-go/ -- [EMAIL PROTECTED] (Kato) _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
