Nice! This one goes to rank #5 in the alltime top 10!

Have you emailed Paul Zimmermann?

Of course.

A c150 is next.
Started the latest CPU polyselect (and the full t45 in parallel), let's see how good it is.

Hmmm.... the DB has 2^4*p9*p20*p28*c118 at iteration 2614 - is this also your latest iteration? has your intended t45 pulled the p28?

Batalov · 2010-12-31, 08:16

Scratch that. Too late, could not edit.
c150 was in i2613 - pulled a p43 before a poly was selected.

Now, a c134 in i2615 - ...anyway, just check the DB. I will be hacking.

Now, a c172 in i2617, -- here's where I get off the train (after finishing all 11e6 curves); take it away with 43e6 curves and so on.

I'll run some slow 43M curves (maybe 24 curves/day....)

Andi_HB · 2011-01-01, 11:04

92 curves @ 43e6 done - no factor

debrouxl · 2011-01-02, 17:57

50 curves at B1=11e7, no factor.

schickel · 2011-02-19, 03:25

The c172 factored as p65*p107. The next line is slightly larger, still with 2^4, and a c155.....

With only a few minutes to spare I didn't have time to divide things up intelligently, so I just started aliqueit and yafu on the c155 independently on two different machines. So far aliqueit has done:

c155: running 74 ecm curves at B1=11e3...
c155: running 214 ecm curves at B1=5e4...
c155: running 430 ecm curves at B1=25e4...
c155: running 904 ecm curves at B1=1e6...
c155: running 2350 ecm curves at B1=3e6...
c155: running 4480 ecm curves at B1=11e6...
plus ~250 at B1=43e6

And yafu has done:

ecm: 25/25 curves on C155 input, at B1 = 2K, B2 = gmp-ecm default
ecm: 96/96 curves on C155 input, at B1 = 11K, B2 = gmp-ecm default
ecm: 204/204 curves on C155 input, at B1 = 50K, B2 = gmp-ecm default
ecm: 408/408 curves on C155 input, at B1 = 250K, B2 = gmp-ecm default
ecm: 1008/1008 curves on C155 input, at B1 = 1M, B2 = gmp-ecm default
ecm: 3000/3000 curves on C155 input, at B1 = 10M, B2 = gmp-ecm default
ecm: 545/1956 curves on C155 input, at B1 = 100M, B2 = gmp-ecm default
