I'll do some poly select this week; this is a small enough job that I can do the CADO select solo.
I'll wait till Tuesday evening or Wed to get started, in case Ryan reserves the job.

I think that 'counting factors' is summarized by the probability the 2*3^2 cofactor is prime, which we're comfortable estimating via prime number theorem (per the post before yours).

Steve-
This is just the sort of estimate we're curious about. If you're able, could you provide those numbers for two different sizes, say 90 and 110 digits? Ideally, we'd want to estimate each...

I did half a t45 on the c192 at i1685. I'll finish the t45 using B1=60M before letting this go.
192 is within reason for 15e queue and the matrix can be solved by Sean or I, but I understand the...

I did 300 curves at 20e6; I think if I were you, I'd stop just before t50 (maybe 80% of a t50).

I'm open to CADOing after you finish ECM; I have enough CADO-cores to sieve it in 3-4 days, though...

i1682 yielded a P34.
i1683 is c155, I'm nearly done with a t40. If someone would like to finish ECM this weekend, be my guest. I'll leave a single thread on ECM until I hear otherwise.

I just got my CUDA rig working again; I'll start at 10M with a low stage1norm (meaning I'll fly through a bunch of a1's). I'll report my best after two GPU-days and decide then whether to continue.
