C181 Poly
 
I will start at 4M on my C181 later today.

RichD 2018-06-20 02:05

C181
 
Nothing in the expected range so far. Still chugging through 4M.

I will help in the poly search of this C181. Does the range 6-8M answer the call?

That would be helpful. I am only a little past 4.5M.

Since post-processing jobs for NFS@Home are now taking in the hundreds of hours, I don't check in as often.

C181
 
Nothing so far - best to date only had a 6 handle. And I had to lower the min_evalue parameter to get msieve to produce any -npr results! Strange...

firejuggler 2018-06-25 00:34

I have a very tiny improvement on the score...

@Firejuggler - Might I ask what values you are using for Stage1 and Stage2 max? I ran a search at c5=94800 with default values (i.e. max) for both stages and did not get the same poly you did (my poly had an awful e-score).There’s a good bit of randomness/luck involved as I understand it, but I’m curious what recipe you used. Thanks.

msieve153_gpu -np1 -nps "stage1_norm=1e26 stage2_norm=1e24 94799,94801"
