Hopefully there'll be bigger turnout this time around. Would love to see CrazyStone and DolBaram compete against Zen.

If you want to see how a bot does given a lot of thinking time, it makes more sense to hire multiple processors than to let it run for a long time. (If you think I am wrong, you can probably convince me of it.) To rephrase what others mostly already said, I think slow tournaments are beneficial on two counts: (i) Implementing MCTS that is scaling well with additional time is much easier than with additional (parallel) processing power. (ii) Some people are already running their programs on the biggest hardware they can find / affort. I think this actually holds especially for the strongest programs where you can't really improve the move quality in any other way than increasing the thinking time. That's also the reason why I wouldn't be particularly excited...

Since I believe most programs scaling with threads will also scale with time (though of course not the converse), I'm not sure if a slow tournament would be more interesting than a regular one with number of cores fixed. -- Petr Pasky Baudis If I had more time, I would have written you a shorter letter. -- Blaise Pascal ___ Computer-go mailing list Computer-go@dvandva.org http://dvandva.org/cgi-bin/mailman/listinfo/computer-go

Re: [Computer-go] September KGS bot tournament: 19x19, slow
It's not easy to code an engine that scales well to a cluster. In 2008 I ahd access to 1024 cores, but the cluster code I wrote at the time only scaled to 32 cores (4 machines, 8 cores each). That code no longer exists, and I have access to a single 16-core machine, so I can't currently run on clusters. With limited development time, I'd rather work on making the core algorithm stronger, than writing cluster code. I think it would interesting to have a slow tournament with a fixed maximum number of cores (4 or 8, since they are readily available).
