There isn't a program that makes efficient use of 8 processors. If they're lucky
the get a speedup of 4, 2 processors gives 1.7, not a big difference.

Even more, afaik they are not playing on a 8 processormachine right now.

That's the point I don't get. Somebody should have told them about the silly
discussion that appear every year with the worldchampionships. Program A will
win because it uses 700 Mhz and program B only uses 550.

Tiger ( and Shredder btw ) has proven to beat multiprocessor programs. It's
about the quality of the program, not the Mhz is uses. Else Zugzwang would have
won more tournaments.
