What is the typical, or average ply depth Deep Fritz (6) calculates per move on your dual machine (MHz?) in a game at 40/2h, or 3 min/move? I can only make rough estimations of the speed increase from dual to 8 CPUs (maybe one of you can make a more precise assumption), but if we can expect it to be *3 times* as fast as a dual - then I think we can also expect Deep Fritz 7 to calculate approximately *1 ply deeper* than on a dual. Is this ok? With that, we would have a better comparison with Deep(er) Blue than by the node rates. From the D.B. logs of 1997, I have the impression that it's typical searching depth was 11(6), or 17 plies, except in the endgame where it was more of course. I think if we base the DF7 estimation on duals from 2*800 MHz to 2*1 GHz, it will be ok because I think the Bahrain machine should have clock rates in this range. Plus one ply and we'll see roughly, what depth gap to expect to D.B.'s depth. If there is one :o) Regards, M.Scheidl
