[QUOTE=BigBrother;318454]I have, there's now a c157...I've done 4500 curves @ 11M.[/QUOTE]
I'll run 7600 curves @ 43M.
Is this sufficient or is there more ecm work needed afterwards before sieving?

7600 curves @ 43M and
18000 curves @ 110M are nearly finished.

So it's ready for poly selection and sieving.

I'll do some polynomial selection on line 5090 then.

Thanks jrk, I'll start sieving + postprocessing.

BigBrother 2012-12-09 14:56

Done. Now a c142, i did 2500 curves @ 11M.

yoyo 2012-12-10 16:00

I'm on the way to run the remaining 2000 curves @ 11M and all 7600 curves @ 43M

Than it should be ready for poly selection.

yoyo[/QUOTE]Thanks for the curves on this!

I tested this with 13e and 14e, and 13e was faster:

I'll start sieving again :)

BigBrother 2012-12-16 10:17

c157....I did 4000 curves @ 11M.
