Edit: Next attempt will be 1.05M to 11M with incr=4620, nq=46656

Edit2: deg 6 scores on the C207 had to be about 20% higher to get the same sieve performance as a deg 5; so this poly (before spin) may perform similar to the 1.05-1.1 deg 5 polys posted previously. This is *not* a sign to move all our search to deg 6! One hopes that if we keep finding 1.09's, Max will spin one to 1.20ish and that will sieve better than a 1.3x or low 1.4 deg 6.[/QUOTE]

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

This hit came from the best-scoring poly after size-opt.
I'm taking a break from this poly select for some time; hopefully we'll have another good deg 5 candidate or two, and Max will stop by to try some spin.[/QUOTE]

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 test-sieving 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 team-CADO-sieve; 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, mid-Nov?).

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 test-sieving in the next 4-6 weeks?

I have a 64GB machine that might do the job. How long is the matrix expected to take (on 32 threads)?

[QUOTE=SethTro;523263]I have a 64GB machine that might do the job. How long is the matrix expected to take (on 32 threads)?[/QUOTE]

I solved a C206 matrix from NFS@home in about 7 weeks on 10 threads of the machine that's hosting 2330L. msieve's matrix-solving process doesn't benefit much from hyperthreading, and is slowed enough by splitting over two sockets that I stick to solving on one socket (I have not achieved joy on the MPI flavor of msieve, which *does* split nicely over multiple sockets; I compiled it but my first try to run it, on that C206 job, produced errors and I haven't tried again since).

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.
