For fun, I re-ran his million-digit calculation last night. What took three years starting in 1987 took 2:21:09 (2 hours, 21 minutes) on a 2006-vintage PC* and 1:38:55 on a 2010 laptop.
I got the same termination message (pass 2415836).

- photon_off 16y agoYour numbers are in near-perfect agreement with Moore's Law, if we take it to mean computation time should halve every 1.5 years. Your 2006 PC is about 20 years newer than the 1987 PC, which means it should calculate it (3 years)/2^(20/1.5) amount of time. That is, based on his computation time, and the amount of time elapsed to the building of your computer, we'd expect your computer take 153 minutes, or 2:32. That's only 11 minutes off of the actual result!
