The three Gimarel's polys from posts 36 and 43 unfortunately don't spin up, sorry.
@swellman: Thank you for the PM.

Looks like we're at 1.39 for deg 6, and 1.18 (with a couple of 1.17's and 1.16's) for deg 5.
I should have some time to begin testsieving in a week or two, at least to try to determine what degree we should focus a last burst of poly select on. 2330L may be in postprocessing before the end of August. I suspect other contributors share my interest in doing some other personal work before doing another teamCADOsieve; I'd be willing to start the next CADO team sieve around the time 2330L yields factors (2, perhaps 3 months after 2330L sieve finishes? Say, midNov?). RDS was pretty adamant that this number should be handled by NFS@home; given the schedule above, I think we wouldn't be able to finish CADO sieving before Spring begins, so I think I agree with him. Does anyone with a 48GB+ machine want to sign up for solving a ~50M matrix for 2330M? It might even fit on a 32GB machine, if that machine isn't used for "regular" work. If so, we should aim to complete poly select and testsieving in the next 46 weeks?

Anyway, that C206 matrix was around 40M dimensions; data is very thin up at C210, but a matrix of 50 to 55M would take 50% to 80% longer than my C206 did. So, 3ish months on 8 cores, maybe 2 months on all 16 cores (or 6 weeks if you find MPI success).

pineapple (i9/7940X, 14 cores, 64GB memory) stands ready to assist.
It has run a 47.62M matrix at density 114 in just under four weeks. (VBITS=256 is very effective on Skylake hardware when you build with a modern gcc)

Excellent! Perhaps someone previously in contact with frmky can ask if early Sept is acceptable to queue this number; we should be finished with poly select within a month.
