Code: For n < 2,400,000 n = digits 2 7 (not a Proth) 142 49 202 67 242 79 370 118 578 180 614 191 754 233 6,430 1,942 7,438 2,246 7,894 2,383 10,474 3,159 11,542 3,481 45,022 13,559 46,802 14,095 70,382 21,194 74,938 22,565 367,310 110,578 485,014 146,010 Due to the lack of new primes, here are some statistics: Largest n in progress = 3.20e6 # of digits = 963,000 (rank: ~ 1000) FFT size = 320k Avg. time = 3140 s Smallest n in progress = 2.45e6 # of digits = 737,500 (rank: ~ 1690) FFT size = 256k Avg. time = 1935 s In about 15 days Mega Prime territory will be reached with n = 3.33e6. In about 30 days all n < 3.2e6 will have been tested. Btw, since the office got a bit warm I have the CPU running with PPT = 128 W instead of 148 W. This decreased the package temperature from 74 °C to 68-70 °C while increasing computation times only by 1-2 %. That's not a bad tradeoff, I think.
