Not with Prime95 version 24. It now support 2^k and 3*2^k FFT lengths on both SSE2 and non-SSE2 machines for 2^n+1 numbers. So it is much better to work only on 2^791+1 now.

I'm using GMP-ECM... It takes 3.5 minutes per curve...

I will do some work on 2,1342L together with 2,1342M (working on 2^1342+1 should make good use of Prime95's length 64 FFT), but I will do 50 digit curves because 2,1342M has already been tested to 45 digits.

Done 1000 curves (45 digit) for 2,951+
I'll do at least 1000 more. |

The required number of curves I posted above was for B2=100*B1; when using the GMP-ECM default B2, the numbers are lower. In terms of fractions, the required work is now
P791: 0.07 (319 GMP-ECM curves or 736 with Prime95) P951: 0.98 (4512 or 10420) P969: 0.41 (1887 or 4357) P993: 0.98 (4512 or 10420) Alex |
