This one doesn't spin up in msieve, need to try CADO on it.

Congrats to Gimarel for finding with msieve, CADO-NFS for spinning it up, and swellman for test-sieving and sending me a PM!
Whoever is actually organizing and performing the sieving (Gregg or VBCurtis), matrix, and solving -- good luck!
I wish I could hang around more often with you guys, but a lot of things is happening at the same time, and all of them are in a good direction. It looks that my next available month will probably be September. Keep sending PMs, I'll do my best.
This is what really interests me right now: https://mathoverflow.net/questions/3...elliptic-curve
I suspect it would be wombatman's (or his colleagues') area of expertise, please pass along.

I suggest you PM Greg with your post; he may be ready to queue it soon.

I am willing to offer some CADO sieving on low Q while it sieves on nfs@home- Greg, I can sieve from Q=10M up to whatever you decide the starting Q is (50M?). I'm not sure I'll get the whole range done, but that should add a couple dozen million relations to the pool. Just tell me what parameters to use so I match the nfs@home effort.

I may use this opportunity to test A=32, which is a 40% larger sieve area than I=16 / 16e. That could get me above 50M relations.

I can request more CPU power from several teams and also would help if you post on the news requesting more power.

BOINC clients prefer to crunch for higher paid sub project not by type of project, and 14e/15e are not on their list. Also I said hundreds of times before that the sub project memory requirements must be updated since 15e tasks use more memory than 16e ones.
