I should have said TD=70 since TD=100 failed. There were only 90M+ relations to start.

I have run into a problem with the relations file for C172_480xx101_19. There must be one or more really bad relations in the file because msieve reads about 134M relations and then locks up.

Can anyone post a Windows executable of remdups4 (or a link) so I can try to clean up the relations?

Many thanks in advance.

It’s the 32-bit version but it’s stable and running only takes a few minutes.

This is really a 31-bit job. You may not have enough resources to run it. Just a thought.

Yes, the poly is actually a 31-bit job. It is mislabeled [url=https://escatter11.fullerton.edu/nfs/crunching.php]here[/url].

This job may lock your machine due to memory limitations. But using remdups may allow you to sneak it through, as well as lower target_density. Sounds like a fun experiment.

I took this number thinking it was a 30 bit job based on the listing in NFS@home, but I certainly will check the poly in the future.

I ran remdups (there were about 20% dups and over 5k bad relations) and was able to get to full merge with TD= 70 where my WIndows 10 laptop with 8Gb memory locked up again due to memory limitations. I then tried TD=60 with Windows booted in safe mode. Then made it to LA with an ETA of 550 hours (ugh!) which is now underway (and I will complete).

Bottom line is that I have to stick to real 30 bit jobs in the future.
