[QUOTE=VBCurtis;446025]That's a pretty good poly score for a composite this size. I think you can just run with that one![/QUOTE]

Thanks! It was a borderline SNFS/GNFS job, guess we will go with SNFS. Appreciate the advice.

Can someone with a GPU rig please help me find a poly for [url=http://www.mersenneforum.org/showthread.php?t=19353&page=4]this job[/url]?

I'm happy to run the GNFS job but with my CPUs such poly searches take forever. Thank you in advance.

I got you. Gonna use the 750Ti on my work computer, though, so I have absolutely ZERO idea how long it might take. Regardless, I'll post something up in the next couple of days. :smile:

Thanks!

Turns out a C142 flies on the 750Ti, so I've actually gone through the entire recommended range. Currently in the root finding stage, but I don't have MinGW (and thus no sorting available), so I'm just running -npr on the entire ms file. Probably will have something by tomorrow?

That's a terrible idea, and will take easily x100 times as long to do. -npr is extremely intensive compared to the first two stages. You really need a narrow it down to the x hundred best candidates. As in, better to pastebin and link here and have someone sort it for you.

Oh, I'm well aware that it's not the proper thing to do--this was purely laziness. If I come in tomorrow and it's still going, I'll just send it to myself and sort/re-run with the top 100-200 hits. :smile:

We're talking at least as long as the sieving itself if not longer. :smile:

You can get away without sorting by setting stage2norm to be about 1/30th the default size. This will produce 100-200 hits/day on a 750ti, on which rootsieve takes an hour or two.

(Kidding around, of course. I had dropped the stage 1 and 2 norms by 1/10 of default choice and limited the minimum e-score to 1.4e-11, so it was probably able to complete more quickly than usual.)
