The end of computer chess. Some math (all rude estimations) 20 trillion is 20*10^12 ins/s assuming my Athlon XP has an ILP of 1.5, and runs at 1533Mhz, that gives 2 299 500 000 ins/s It runs Rebel at about 700knps, so a node needs 3285 insns. The Blue Strom will run at 6 088 280 061 nodes per second times 3 minutes per move 1 095 890 410 980 nodes per move Assuming an overall branching factor of 4 (this takes into account parallell efficiency): it would search...(drums rolling)...20 ply I think chess can survive that. -- GCP
