Chris[/QUOTE]

My bad - there are two fields used by NFS@Home: “Name” and “Display name”. When adding a new factoring job, only Name is input. Display name is auto filled with the Name value, with the exception of the 15e_small siever which leaves it blank. One just fills in the desired Display name. I must have inadvertently truncated it during the cut/paste operation.

In an abundance of caution, I will hold off editing Display name for this job until the factors are reported and the job is moved into completed status.

I do not know why there seems to a problem with sieving C172_434040_3112. I test sieved up to Q = 200M and there should be about 260M relations for the Q range (40-130M) that I chose. Sieving is almost complete and there are only 150M relations. Any thoughts?

Results from 5k test sieves:

Q Relations
20M 8161
50M 13218
100M 15524
150M 16651
200M 15336

Add another 70M Q (130-200M)?

Yes, I believe I’ve located the problem. In your original [url= https://www.mersenneforum.org/showpost.php?p=573028&postcount=104]post[/url], you had a line “lss:0”, but it should read “lss: 0”. Msieve is apparently ignoring this line in its current erroneous form and is sieving on the rational side.

I should have caught this typo but did not. My apologies.

Moving forward, I can

A. Fix the typo and see what happens.
B. Ignore the typo and extend Q further
C. Let this job finish and start another job called C172_434040_3112a with the correct syntax and sieve on the algebraic side albeit over a smaller range. You can download both data files, combine them and proceed with LA.

A is the fastest option, but there’s a chance Greg will have to intervene if something breaks.

Any suggestions? Greg?

It's actually the ggnfs sievers that are ignoring the line, not msieve. The real longer-term solution of course is that the sievers shouldn't be so fragile that they require a space after the colon on every line of the .poly file. But they do.

So as far as immediate solutions for finishing the job go, I suspect that C would actually be faster than B. A is a bit of an unknown quantity, because I don't know exactly how NFS@Home will handle a change like that. My guess is it wouldn't have any effect, since it thinks that it's already handed out all the work. But it's up to you and Rich, of course.

Sean, I would prefer to work with just one file, so I'll do some test sieving to see how many more Q we need on the rational side to get to 260M relations. And it was my fault for missing the space.

Ok. I’ll add 20M to the range immediately, just keep the job moving.

At this point I recommend to just keep going. You'll probably need to sieve to about 200M. Not a big problem, really. :smile:

I estimate we will have to go to 230M based on test sieving.
