Default 2,2630M (C193)

Now running CADO in parallel to my msieve-GPU effort. First run used

Code:
tasks.polyselect.degree = 5

tasks.polyselect.P = 8000000
tasks.polyselect.admin = 1e4
tasks.polyselect.admax = 5e5
tasks.polyselect.adrange = 3360
tasks.polyselect.incr = 840
tasks.polyselect.nq = 15625
tasks.polyselect.nrkeep = 160
tasks.polyselect.ropteffort = 45
Resulted in
Code:

Not a great polynomial, maybe it can be spun higher.

Next run will use incr of 4620 and adrange 18480, searching admin 5e5 and admax 5e6, with P and nq unchanged.

I see the best poly for 2,1437- was found by @VBCurtis and scores 1.43e-14 (in post #2015).
2,1437- is queued for sieving.

This a minimally acceptable e-score for a c180. I’ve just thrown msieve-GPU at it in an attempt to find a better poly but we may search for a long time to get a 5% better poly.

Maybe the spinners can raise it a few percentage points? Max? Ed?

Great! Is anyone still working on 2,1404+ or 2,2630M? It appears we have good polys for both now. That just leaves 2,2870M.

Thank you, Sean! I'll test-sieve both polys.
