Team sieve #23: c172 from 4788:i2617

schickel · 2011-01-07, 10:39

Post-processing started: 10 Feb 2011, ETA evening of 17 Feb 2011 Pacific time
Post-processing finished! c172 = p65*p107

After a lot of heavy lifting from bchaffin and Batalov, we have now come to a c172 on line 2617:

Code:

2229348552361822129355877431354933637944777944345113399577912185681707793442268713514615675586421258420770429669349552195250785917635169750211125857968489791489287723679679

We have run a lot of ECM on this, so it should have a really nice split.

Code:

n: 2229348552361822129355877431354933637944777944345113399577912185681707793442268713514615675586421258420770429669349552195250785917635169750211125857968489791489287723679679

I just see that yoyo@home has finished 5000@85e7.

Time for GNFS - reserving 25M-26M

bchaffin · 2011-01-23, 01:25

I'll take 26M-35M.

EdH · 2011-01-23, 02:17

I'll try 36M-37M. . .

That was silly - I meant 35M-36M.

Put me down for 35-37, then. I'll have two machines churn away for awhile and see what shows up. . .

I guess it drops down the forum when messages are removed.....maybe we should leave the most current message so the thread doesn't get lost?

We usually leave all posts there, so there's an easily visible record of everything. I don't see any reason to change that standard, especially since, as you mentioned, it drops the team sieve down the list. I'll go ahead and undelete those posts for now.

Hmmm.... OK, should be no problem do 24-25M additionally to my original reservation.

Does "on algebraic side" mean an additional switch?

I used:

Code:

gnfs-lasieve4I15e -a 4788_2617.poly -o 4788_2617.rels -f 35000000 -c 1000000

That line looks fine - the -a means it sieves on the algebraic side.

Thanks! I just happened upon that information in another thread, too. I guess I "a"ccidentally got it right.

I'm not sure where switches can be found. Is there a document somewhere, or a switch to show switches?
