Chris

Done.

I'll do the LA.

NB. Does it matter if 15e_small runs dry? It's been a while since anyone else submitted any jobs to it.

It won't. I have a few jobs lined up, for one- but the queue has been pretty long the last couple weeks, so I haven't submitted. If it does get close to dry, we'll just post one of the smaller regular-15e job to it.

Test-sieving 1kQ intervals on the -r side indicates a Q-range from 20-160M should be sufficient to produce 415M 32-LP relations. My tests indicate 32 is faster than 31, even though 31 is normal for this size of job.
