All good these things happen. I must admit I did think that's an interesting way of spelling my name :)

Mon Jul 13 10:30:52 2020 filtering wants 1000000 more relations[/CODE]
With just over 700,000 pending rels remaining. My question is does this job require more sleeving?

What target density did you use?

Mostly likely it needs more relations. I can bump Q up to 45M. That should be sufficient but please let us know if it won’t build.

ETA: Q bumped up to 45M

My apologies I forgot to put I use TD=120 thanks for bumping up to 45 million

And f17_202p1 has built a matrix. About 175 hours remain.

Small jobs don't benefit much from high target densities. Try TD =108 and TD = 120 once you have the new up-to-45M relations, and see for yourself. Even TD = 100 is unlikely to take more than an hour more to solve the matrix than TD =120.

Thank you for your input. I managed to start job with a TD116 to do that LA phase it's going to take.

Tue Jul 14 11:43:55 2020  commencing Lanczos iteration (23 threads)
Tue Jul 14 11:43:55 2020  memory use: 2270.0 MB
Tue Jul 14 11:44:00 2020  linear algebra at 0.0%, ETA 2h55m
Tue Jul 14 11:44:02 2020  checkpointing every 1230000 dimensions

This is slightly longer than the "hour" you refer to solve matrix, I like to do the LA phase of the job in the shortest amount of time.
Roughly 35% complete with a 1 hour 55 minutes to go

I ended up running number with a TD116 took just over 3 hours and 37 minutes. Find zipped log attached

p51 factor: 165575181446411460205828705575691615869005925901441
p106 factor: 7185207381967777817292364114317982628364500160381105212878698339416404696843526675114572666774815941222461

I have added to factor database

You misunderstood- I said a lower TD would take less than an hour MORE than TD 120. I made no promises about how long the whole job would take!! (How could I, since I don't know your hardware?)

If you try the same job with TD 104 or 100, I wager the ETA won't change by more than 10%.

Very good point. Thank you for explaining I understand now and please accept my apologies

TD 120 built a 3.73 M matrix which took 5.57 hours to solve (TD 130 didn't work). Log posted at https://pastebin.com/zY842gvE and https://github.com/Dylan1496/nfs-at-...__587_11m1.log.
