Mersenne: 1000 barrier
I've been with GIMPS for about two years and yesterday achieved a personal milestone; I finally broke thru the 1000 barrier and made it to 996 on the top producers list. Each step forward is getting smaller and smaller though; I think I'm approaching the knee of the curve and will eventually start going backwards.

Mersenne: Mlucas FFT Timing Questions...
Does there only need to be one FFT line in mlucas.cfg, for the one that matches your exponent, or do they all have to be there? I've run tests for the FFT that matches my exponent (352K), but I really do not want to run tests for all of them... Especially since there are two possible binary versions for my system... The times between having error correcting on and having it off are not that far apart in some cases... The shortest non-error corrected time (33.4s for prefetching off/radix 2) is very close to the shortest error corrected time (36.0s for prefetching on/radix 6)... In this case would using error correction be advisable? Thanks!
