Grr, that's irritating, and I can't fix it through the management interface: Greg will have to do it. It would be nice to forbid colons in task names at the job-submission stage.

I guess if we're only getting Linux sievers that would explain why it's going so slowly.

Yes, apologies for mucking that up. I was never given any information about what constituted legal characters for the name.

As for the parameters, they're not great but as you've suggested I don't think that's the reason it's sieving slowly. The yield is within a tolerable range. It's just that there are very few work units being done. The status page has been showing alarmingly low numbers of pending units for a while, and I didn't have an explanation as to why. Now I do.

Can we get Greg to cancel outstanding work units, then re-insert the number with a new name? And if that happens, is there a way to carry over the relations that have already been found?

The 14e queue is behaving normally except for the last entry. Nothing is moving from Pending to Received. This has been going on for hours and hours. May be nothing.

No, it's not nothing. Thanks for pointing that out. The original request for this number included the polynomials/parameters, which I just copied into the form. Unfortunately it contained an errant line break in the middle of the "n:" line. Added anew.

If Dmitry doesn't mind, I'd be inclined to download all the relations found so far, delete the job, do the rest of the sieving with my own resources, and run the linear algebra myself. Would that be OK?

It's ok with me. According to status page now about 96% of sieving were done.

I presume this is C222_125_92b. My cut/paste submittal but I have no idea how a random line break got into the mix. My fault for not noticing it. Apologies to all. Won't happen again.

Test sieving on the -a side for 10K range at various Q starting values were as follows:

Q_start yield
150M 2.17
300M 2.15
450M 1.81
600M 1.80

alim of 450M seems to work nicely, but perhaps it should be 500M. This factorization is outside my comfort zone.
