ECM for c166 from 4788:2661

frmky · 2011-04-06, 02:18

It's done [c116 from line 2660]. Just started ECM on a C166.

Target is t55 (18k curves @ 11e7 or equivalent). Work so far:

p-1: B1=1e9, B2=1e15, no factor.

I've done about 2000 curves with B1=11e6, and three P+1 runs with B1=1e9, B2=1e14.

jrk · 2011-04-06, 20:11

I've started polynomial selection.

Probably need about 18000 more ecm curves @ B1=11e7 before sieving.

Andi47 · 2011-04-07, 04:59

p+1: 3 runs at B1=1e9, B2=1e15, no factor.

No factors.

+3000 @ 33e6, no factors

Scratch the previous poly. This one is a bit faster.

How much ECM has been done so far?

I consolidated the counts so far. I've also set up to run some curves @ 43M.

Andi47 · 2011-04-10, 05:51

I also have just started six threads to run curves at 43e6

Looks like I can manage close to 1000 curves a day @ 43M....so 1000 so far.
