Deep Blue utilizes the IBM SP Parallel System called MPI. "It's a message-passing system," says Hoane. "So the search is just all control logic. You're passing control messages back and forth that say, well, what am I doing? Did you finish this? OK, here's your next job. That kind of thing at the SP level." I also seem to recall that in the first match, the programmers tweaked the software between games. How could this be done in hardware? Nobody would go back to a game with newly burned chips that did not have significant tests. But a small tweak of the software, piece of cake. What am I missing here Robert? KarinsDad [snip]
