[QUOTE=swellman;561552]I have no issue enqueuing this job even though it’s a touch over the difficulty and Q range limits for e_small. Any objections?[/QUOTE]

Where ever you think is best for balancing the grid.

VBCurtis 2020-10-30 16:07

I don't think the Q range nor LP size should be the deal-killer for e-small; but since memory use is advertised to BOINCers and overshooting the claims of memory use on 14e was a topic of complaint from the users previously. We should be hesitant about putting lim=134/268 jobs onto e-small.

That said, with one of these BOINC-competition things firing up, feeding the grid is more important this week than strictly following rules, so I point this out just for future "normal" times. E-small is more likely to run out right now, so we feed it.

I'll test-sieve a couple more jobs around SNFS-265 today, since it looks like the BOINCer army has arrived.

And FWIW, I have several jobs with difficulties in the high 250s that are probably actually within bounds for 15e-small. I'll work on getting a few test-sieved.

Suggesting sieve range is 40M-140M, I'll take the LA.
P.S. This task is slightly big for 14e queue within new guidelines, but you decide because 14e is almost empty.

VBCurtis 2020-10-30 20:46

We like 14e empty, and C172 is definitely within e-small guidelines. Good choice.

RichD 2020-10-30 21:31

[QUOTE=VBCurtis;561562]We should be hesitant about putting lim=134/268 jobs onto e-small.[/QUOTE]

That was my fault for suggesting e_small. I seem to remember the 200 average lim but that is for 15e, not e_small.

I won't have anymore for e_small and 15e is currently building a long line.

VBCurtis 2020-10-30 22:05

During BOINC-challenge time, e-small was the right choice there for the job; with the benefit of hindsight we might just choose 134/200 or 134/180 for such a job, giving up a bit of speed to keep e-small fed without going too far over memory guidelines.

Your job surely did less damage than my bad poly on 5_791m1!!
Here's a corrected job for that number, with the full composite on the "n:" line:
