I had a power dip during a thunderstorm that crashed the system doing the LA. Which delayed it a few hours and lost the total time (it took about 128 hours in total).

The relations file for 165__521_7m1 seems to be truncated due to the Pentathlon craziness. There are only 33M relations so about half are missing in action. Any suggestions?

Is this relations count confirmed via download and running msieve? We can bump up Q to generate more rels of course but is the data displayed correct?

Give me 15 mins, will give you an answer. On filtering stage.

Thanks Carlos. I’ve bumped up Q by 10M for now, goal is ~65M rels.

Should go quickly.

Sorry I had gone to bed after my post. Yes, I had downloaded and filtered the relations file with msieve. I think we will need more than 10M additional Q.

Sat May 22 15:19:24 2021 filtering wants 1000000 more relations[/CODE]
Is it worth bumping this number up or should I wait for all rels to be returned & try again?

What target_density did you specify when starting msieve? Or did you just go with the default value (TD=90)?

There appears to be plenty of relations for a job this size but who knows with the recent tsunami resulting from the pentathlon.

165__521_7m1 is in LA. ETA tonight (or tomorrow morning if I fall asleep).
