Distributed processing is something not many programs have used well, or even at all. I think there was something called Sun Phoenix back around 1985? Was Shaeffer involved? And Deep Blue, but that thing had such an enormous amount of speed it is hard to say if the distributed processing was used well or not. I think Hsu published that he got 35x speedup with 100 cpus. I suspect that's not as easy to do as it sounds, but it also is not as good as you'd like. The few other examples haven't exactly set the world on fire. Bob Hyatt has been one of the people pointing out that efficient use of distributed processing is difficult or impossible. Bob was one of the first and still one of the most successful with small scale SMP (but maybe not for much longer ...). And Cray Blitz was probably the only program to make good use of a vector unit. Maybe after a bit of tuning and experimenting, we will see an efficient distributed processing chess program.
