GMP-ECM @ 50 digits:

Stage 1 = 10m29s
Stage 2 = 10m16s

207MB used for Stage 2...

The same. you're trying to factor the same number. It's just that some known factors are left out.

Code:
815  (5,163)                                                            C195
The numbers in brackets refer to the algebraic factors (2^5-1 and 2^163-1), the ones outside the brackets (none in this case) were found by computation.

I think that if you use gmp-ecm on the C195 it will recognise that this is a factor of 2^815-1 and do the actual computation on 2^815-1 if that works out to be faster.

To celebrate the holiday season, I ran 1000 curves on M815 during the last few days:

[Tue Jan 04 19:23:50 2005]
M815 completed 200 ECM curves, B1=44000000, B2=4290000000

[Tue Jan 04 20:48:24 2005]
M815 completed 400 ECM curves, B1=44000000, B2=4290000000

[Tue Jan 04 21:12:30 2005]
M815 completed 400 ECM curves, B1=44000000, B2=4290000000

Now it's time to return again to my normal exponents (which are slightly higher, actually)!

Arjen.
