you might be encountering false sharing by making every thread edit that single location in memory. if you get rid of the writes you might see a drastic performance increase. or you can actually use bucketing.

Pure CFR speed

2014-10-07T02:08:59+00:00

Recently I've read Amax' post in the old forum, where he said, that his CS-CFRM algorithm runs at 550k iterations per second.

I have been using the pure cfr open source code and even when I completelly diasble bucketing and hand evaluation, which means I just always return 0 (for testing purposes, of course this gives wrong results) I only manage to get about 30k iterations per seconds, even with multithreading. So even just the recursion through the tree takes way longer.

Is the algorithm just inefficient? What can I do to speed it up?
