Currently Many Faces' strength peaks at 32 cores, and goes down with more. On a single core, strength increases 50 to 80 ELO points per doubling of performance. On multiple processors the rate of increase is much less. The increase is very sensitive to communication latency, so a [EMAIL PROTECTED] type of engine is unlikely to be much stronger than a single computer or local cluster.
The 32 core machine I'm using has 40 Gbps Infiniband interconnect with less than 2 microsecond latency.

So, when are we going to see distributed computing? [EMAIL PROTECTED], [EMAIL PROTECTED], [EMAIL PROTECTED] With Go engines that scale well to increased processing capacity, imagine facilitating a few thousand PCs to do the computing. For good measure, [EMAIL PROTECTED] as about 800,000 nodes online as of now. What's the approximate increase in playing level per increase in processing power? Any rough law for that?
