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. This % is quite boring and complicated :-) The % decreases with tim

Is the true scalability of mogo (against a variety of programs, or against people) less than the rating study indicates? Unfortunately, I think that the answer is yes (very very). In particular the tuning has been performed on small games, and I guess the new very fast (parallel) versions of mo
