So what would it take to get corporate sponsorship of the sort which drove the chess computing field? Where is the Go equivalent of Deep Thought?
The Japanese Govt and industrial sponsorship of the Fifth Generation Project, which did have playing Go on its list, collapsed very soon after the Japanese real estate bubble burst, over 15 years ago.
Near as I can tell, David Doshay's Sluggo is the only large-scale parallel effort. Mogo uses at most 4 CPUs. What might be accomplished with one of the top500.org clusters of hundreds or thousands of CPUs?
Corporate sponsorship would be required for access to a top500 cluster, but for a smaller scale attempt I have already offered the 72 CPUs in my largest cluster for a scaling study. Nobody took me up on the offer, so I gave the time to a physics computation. That computation should be done in less than a month, and I will repeat the offer now. We can also put a few of my clusters together and scale up a bit more. However, if nobody responds in a short while, I will again turn the cluster back to physics. If you have a MC-UCT code that can scale up to multiple CPUs then contact me off the list. I am open to collaboration. Repeating my experience to date: with the algorithms in use by SlugGo, more that 20 or so processors and deeper lookahead than just a few moves not only does not play better, but it plays worse. MC-UCT clearly has better scaling behavior.
