Well, what I remember is that they reported around 400M nodes peak and 200M nodes average. Anyway, a factor of 4-16 is not something I consider very much, it isn't more than two to six years of Moores Law. :-) However, it is still an open question how good DB was at evaluation. Those guys were smart and could throw silicon at the eval terms, so it's possible that they had significantly better eval than state-of-the-art chess software of today. On the other hand, it's possible they didn't. However, in six years, chess software should have progressed somewhat, there will probably be six man EGTB, much more RAM for hash tables than DB had, and an architecture that allows more efficient parallel search than DBs. Thus I think it will be possible to have a DB strength chess machine on a general purpose high end server in six years from now. How well does your SMP algorithm scale, by the way, if you don't mind me asking? 64 processors are quite a lot. Jesper Antonsson
