Similar in concept to Belle, HiTech and Deep Thought/Deep Blue. Not X86 based at all. Not portable to X86 either. Of course other examples include "chessmachine" by Ed, using (I think) an ARM processor many years ago. > >please explain what is so hard about the simple idea of announcing well in >advance that a dell(for example)computer running on a xxx mip computer with a >yyyy processor will be the hardware used >all entrants will have their programs installed on the tournament hall >computers before the match > >now i realize that in the early days with hugh mainframes you could not possibly >expect Kaissa to use the same hardware as Chess 3.5 but today? > Some commercial programs are written in assembler. Is it necessary to pick X86 simply because they are in asm? Or can we use MIPS, Opteron, SPARC, PPC, Alpha, Hitachi/IBM, Cray, etc? What about the person that uses bitboards and writes for 64 bit machines? You make him run on a 32 bit machine? What about the person that takes the time to do a parallel search? Make him run on one CPU and throw all that work away? What about the program designed for a vector machine? Not allowed since X86 is the chosen platform. this is nowhere near as easy to do as it seems... >or is it, that this would force all programmers to go out and buy the same >system to be used at the tournament site and it would cause a finanical hardship >? > >Steve
