Yes, I figured it would be somewhat on the borderline depending on timezones, so that's why I specified the date in my post specifically to be 4/21.

Meanwhile, I'll get the postprocessing started up shortly.

Well, would you know! Apparently msieve wasn't satisfied with the ~21M relations we've collected:

filtering wants 1000000 more relations

Looks like we'll need another 1 or 2 million relations. Load 'em up!

You're right.....I didn't go back far enough when I changed it to "awaiting post-processing".....

I should have mentioned this at the time, but if you have a skew of half a million, as you do in this case, the aspect ratio of the line-sieving rectangle ought to be 500000:1 ... so b=1..2500 would mean you'd want to target a=-625 million .. +625 million.

Lattice sieving remains noticeably more efficient than line sieving.

Well, believe it or not, we still don't have enough relations:

filtering wants 276621 more relations

Probably another million or so should do the trick.

What is important is how many unique relns you had at this point.
(Check the log. Then you may be able to make a better estimate.)
For a number of this size, you'd need at least 20-22M unique relns.

filtering wants 276621 more relations
is not always accurate.
