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
http://www.rechenkraft.net/yoyo/y_status_ecm.php
Than it should be ready for poly selection.

Thanks for the curves on this!

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

I'll start sieving again :)

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