2022  queue management for 15e_small
Going forward, please post all 15e_small work to be queued here, and ONLY 15e_small work.
(Please note that 15e queue management now has its own thread.) Guidelines: Jobs clearly faster on 14e can still go to the d queue; if there is any doubt whether 14e or 15e is faster, post them here for 15e_small. Candidates for 15e_small should use lims no higher than 134M and Qrange no more than 180M (example: 30M210M).

I thought the main esmall requirement was lim's averaging 134M for small memory use. This job uses the full 15e lim's averaging 200M.

Sorry, the tempo of the BOINC challenge got to me. It’s too late to change it as it’s entered sieving but it was a completely unforced error. I’ll ask to Greg to intercede. He can kill it and we can move it to 15e.

With yield under 1.5 and that wide a Qrange, you're likely to get an unpleasant duplicate ratio. A job this size really calls for 32bit large primes, and I imagine 3LP on one side too. I bet yield is quite a bit better on full 15e a C182 is clearly in the upper half of jobs where 15e is optimal, making bigger lims pretty useful.

Did you try it with 3 LPs? That’s allowed on 15e_small 31bit jobs. I have no idea if doing so would increase yield enough to generate enough rels within the allowable Q limit. (15e_small is really meant for small jobs  a GNFS 182 may be too difficult for it.) But I’ll be happy to enqueue it on 15e if you’d prefer.
