[/code][/QUOTE]That was some heavy lifting there. :flex: Thanks for the enormous boost!

And so with that, another 17 lines added very quickly and the 160 digit line has been breached! (And there's a c136 -- almost a yawner!)
:party: :party:

Done 4800@1e7 on the C136, which I think is about enough (it took about 83 CPU-hours and the sieving should take about 200 on same hardware).

Am leaving the sieving to someone else.

I can do this if no one else does. I'll have to put my current job on hold....(I'll start it tomorrow if no one says they're going to....)

schickel 2011-12-19 04:50

OK, I ran a poly search while I was at work today, and since no one else has said anything, I just kicked off the job for this. ETA is maybe 3 days? (It's been a while since I did one this size, so I'll know more for sure tomorrow....)

The factors are in the DB - have you send the factors Schickel?
New 137 digit composite at line 2789 now.

Did 3000 curves at B1=10M on the C137. Assuming that others have probably also run some curves, I'll go ahead and start GNFS on it.

jrk 2011-12-21 03:42

I did 1154 curves @ B1=10000000, B2=46842680440 on line 2789 c137

The C137 splits as:
[CODE]
prp65 = 92604252360612149566142017110232157485024433471209368898867397209

A fact I discovered over at factordb.com while my sieving effort sits at about 95% done.
