Just to report some curves: I ran 800@11e6 and 300@43e6 on the i2081. The p40 split of fast, but there is still a c129 remaining.

EdH · 2013-08-19, 22:12

I've been beating up on the c129, as well. So far, I've have at least:

3900@11M
2000@43M
1200@110M

But, I'm rewriting some scripts and probably have a fair amount of extra curves that aren't in the above counts. I've also started YAFU in a factor() exercise that ran lots more curves and is now doing a poly find.

EdH · 2013-08-21, 02:04

OK, the c129 is done and added to the db. There's now a c126...

YAFU just switched to poly select.

I'm playing with factmsieve.py, msieve and some new scripts that are working on the c126. Right now, I estimate factors by sometime tomorrow, if you'd like to move your machine(s) to something else. Or, I could let you post the factors when you get them. My setup is far from where I want it and if you want to run with this one, I'll step back...

Sounds like you need a number for testing anyway. Might as well be productive. I'll redirect mine now.

EdH · 2013-08-23, 03:49

Thanks - almost all the sieving is done. I don't know how long the LA will take, but it shouldn't be too much of the night. I should be able to post factors in the morning.

The new scripts are taking on a workable form, although I keep missing important details...

EdH · 2013-08-23, 13:16

Well, I should have had factors waiting for me, but NO-THAT WOULDN'T BE RIGHT!

Instead, I find the power company was, yet again, incapable of providing uninterrupted service. Ah well, another opportunity to learn how to restart in the middle of the LA phase, since I obviously haven't learned how, yet. Off to uncompress spairs.save.gz, since my first attempt removed all the relations from the .dat file...

Then, again, I think my system needs some more tuning anyway:

Code:

Fri Aug 23 01:18:57 2013 Found 42310375 relations, 259.9% of the estimated minimum (16280000).

If anyone is running curves you can add my contribution.

-pm1 3e9 - nothing.

900 @ 43e6 - nothing.
I should have 2500-3000 total by morning.

Never mind.
