ECM for c166 from 4788:2661
 
It's done [COLOR="Blue"][c116 from line 2660][/COLOR]. 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.

frmky 2011-04-06 19:55

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.

+2000@43e6
No factors.

+3000 @ 33e6, no factors

new poly for aq4788,2661
 
Scratch the previous poly. This one is a bit faster.

Sieve with 15e on -a side from Q=16M to 52M

How much ECM has been done so far?

[QUOTE=jrk;258052]How much ECM has been done so far?[/QUOTE]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

[QUOTE=schickel;258061]I consolidated the counts so far. I've also set up to run some curves @ 43M.[/QUOTE]Looks like I can manage close to 1000 curves a day @ 43M....so 1000 so far.
