A good SMP alpha machine can hit 5-10M. IE a 16 cpu machine would do this quite handily. But it wouldn't be cheap. As far as 200M and beyond, I don't know if there is hardware that will do that yet. That is a _load_ of computing power. > >#2.) On IBM's AIX platform, is there anything special that would need to be done >in order to run Crafty from it? > Yes. The SP is a message-passing architecture. There is a current project underway with several computer vendors called "the Universal Parallel Compiler" that can use message passing to implementa a slow form of shared memory without the programmer having to do any explicit message-passing. I am working on this right now because the larger compaq cluster machiens can use this compiler. > >I will _possibly_ be getting (and by getting I mean, passing through my hands) a >RS/6000SP system that would actually be faster than the hardware that Deep Blue >II ran on.
