Hmmmm... on my C2D CPU, poly selection would take ~45 hours, and I have no suitable GPU available.

Anyone with a suitable GPU for poly selection?

[QUOTE=Andi47;200126]Anyone with a suitable GPU for poly selection?[/QUOTE]
I will run it for about a day.

2000 more curves at B1=11e6 done, no factor.

3e-11 is a good score for this number so I am stopping the poly search.

Sieve with 13e from Q=5M to Q=20M.

I'll take this one. Thanks jrk!
Should have factors tomorrow.

Sieving and the linear algebra took about 8 hours, but I had to sleep on the square root after it [URL="http://www.mersenneforum.org/showthread.php?p=200311#post200311"]crashed [/URL] in msieve version 1.44. An older version of msieve (1.42) completed the factorization.

Not in the DB yet, as it seems to be down.

we have now:

next line is 2^5*5*237607*c164

[CODE]c164 =

(not yet in the DB as it's still down)

Will throw some 1e6 curves at the c164.

i am doing p-1 to 1e10

[QUOTE=henryzz;200330]i am doing p-1 to 1e10[/QUOTE]

Which B2?

[quote=Andi47;200333]Which B2?[/quote]
dunno havent decided yet
at least the standard B2 for a B1 of 1e9
as much as i can fit in memory for first go i expect
i might do extend my original run of stage 2 though
considering how much ecm we do on the larger candidates i think we dont do enough p-1
