Cray 1 is 1e8 in 1978 and we're now at 1e15. It's not a uniform graph. Interesting that we hit 1e12 in 2000 or so and are now at 1e15 ...I built a 10T in 2002, so there is a slight slowing, but not much. But those Cray 1 vs. cluster FLOP numbers are different. A Cray 1 vector flop rate is not easily compared to a cluster flop rate. For $1m you can get a 40T system; the japanese earth simulator, 30T, probably cost about $500M to build including all costs. It's going to really ramp up with stuff like the Intel systems coming up. thanks ron
