One from the [URL=http://www.lirmm.fr/~ochem/opn/mwrb2000.txt]MWRB[/URL] file.

I'm thinking the Q range should start at 30M or 40M. Just a gut feeling, that's all.

I have many ready but I don't know what the grid is looking for. I mostly focus on 14e since 15e seems to have plenty. Don't want to hog the 14e queue.

richs 2017-03-07 17:17

No tasks are available on 14e at the moment.

If 14e needs some, here's a few repunit ones:

Just an observation
 
[QUOTE=fivemack;454482]51119_250 queued on 14e (same applies)[/QUOTE]

The poly file for C250_51119 contains both "lss: 0" and "type: snfs" which appears to be contradictory. With the relatively smaller coefficients I would think the sieving would still be on the rational side. Maybe not. Just pointing out a possible abnormally.

Typo: C237_12119_59 should be an SNFS(245) - not 254.

richs 2017-03-08 21:07

I would like to post process C171_829332_3638 (VBCurtis offered to help me as needed).

Whom do I contact to get access to download the relations once the sieving is complete?

Thanks!

RichD 2017-03-08 22:27

Send a PM to Greg (a.k.a. [B]frmky[/B]) saying you would like to have access to the data for post-processing. He just wants to know who has access.

Any of the regulars in this thread would also help out with questions you might have.

For C250_51119, I did test sieving on both sides and algebraic-side was marginally quicker.

I've fixed the typo; thank you.

I review most of these larger jobs as a learning experience. It seems this one would be another potential job for performing part of the sieving on each side but that mechanism is not in place today. :)
