Ooops, you're right, only 15 minutes. I guess I had a spot of lysdexia there when I first posted..... Anyway, as Batalov said, he'll have the composite cracked overnight, or you could get a lucky strike if you leave your cores running overnight, so it works out either way.

At some point in the future, yoyo, you'll probably want to add a program for GPU-based (CUDA) ECM stage 1: GPU-based ECM stage 1 is still a bit experimental, but it can easily be faster than CPU-based ECM stage 1

Done. Next is c122, will do too.

320 @ B1=3e6 run about one hour ago on the C147, no factors.

Batalov · 2012-03-31, 18:54

We would need 7000 43e6 and a poly.
I started some 43e6s.

I'll pitch in 1500 or so.

I'll do a poly.

I got 2000 43e6 curves so far.

Does one of the usual suspects want to make a unilateral sieve, or should RSALS do that ?
