Suppose Blue Gene were to be turned on the task of GIMPSing. To my knowledge, there is no way to get a million one-gigahz processors to work as one petaflop machine, so we would not get a residual of a ~2^8E6 Mersenne in 1.5 seconds, but we *could* theoretically give it a million exponents and get the first ones back a couple weeks later, and have all million back within five months, in which we could expect ~4 new Mersenne primes, representing 38 years of our efforts, currently. Wouldnt that be kewalllll. {8-] spike _________________________________________________________________ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
