Yes, and this poly gathered 6% less relations than poly with 1.132e-13 score from https://www.mersenneforum.org/showpo...postcount=1995

Done; 1.36e-14 was best from run #3. I'm done with the poly select for 2,1437- C192.

I'll start on CADO selecting 2,1404+, also a C192.

Continuing search of 2,1437- with msieve-GPU.

It didn't get any better score from spinning on my system.

VBCurtis · 2021-07-03, 18:36

Run #2 on 2,1404+ was 10% worse, a 1.46e-14. I did the runs in reverse order, so incr=210, ad range 50k-2M, nq 15625, P = 4M was the lousy result, while 2M-40M with incr=4620 and the rest the same was the better run.

I'll try 40-80M with P=6M next and incr=4620.

swellman · 2021-07-04, 16:46

Found nothing worth reporting on 2,1437- (C192). I’m done searching for this poly.

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

I ran msieve-GPU poly searching on 2,2630M with c5 < 300k but found nothing worth reporting.

Now searching range 15-16M using msieve-GPU.
