Still nothing in the expected range or better than previously posted. Taking 1.5M-2M.

RichD · 2016-12-30, 05:08

It is getting a little better. Continuing on down to zero.

Really good poly. What on earth made you look above 1e9 for it?
I am "generally" getting better results the lower I go.
Though nothing better then my last post and I only have the range 2-300k to go.
It should finish within 24 hours.

Gimarel · 2017-01-03, 11:08

It was an experiment with a very smooth leading coefficient.

RichD · 2017-01-04, 00:14

I have completed the range up through 6M with nothing better to report. Giving up for now.

VBCurtis · 2017-01-04, 04:00

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.

VBCurtis · 2017-01-10, 18:17

4.5 GPU-days on a 750ti got me 29 hits below 2e25, and a best poly score of 1.569e-14. Not competitive. I -npr'ed hits 5e25 or better.
I ran from 10M to ~15.4M with stage1norm just under 3e27.
This ends my effort on this number.

swellman · 2017-01-18, 20:08

So is Gimarel's poly the clear winner? If so I'll do some test sieving and propose it for the 15e queue.
