Quick update: slow is my progress. My normally “fast” script crawls at 1000 c5 per hr. Running 1-16,000 yielded 5400+ polys to be -npr’d! :buddy: Still chewing on that batch but I’m abandoning the script.

I’ll run my other script - it gave me a record on the C195 from AS 3366 and was much faster with less garbage retained for -npr.

C197
 

I'll be out of the loop for the next four days, sorry. I tried C197 with yafu on CPU, saw a lot of 2's and maybe an occasional 3. If any of you got to a 4e-15, it's already better than CPU yafu. Just post your top E score from time to time to track the progress.

looking for a C191 candidate
 

There is a dive in the top score table for a C191. My old poly 1.581e-14, July 2016, 10,429- was apparently never a record (see c191 links at [URL]http://cosweb1.fau.edu/~sbai/[/URL]). Anybody has a good C191 candidate in mind?

C191 -- resolved

This is not my work - I merely nominated it for NFS@Home.

Well, my other script is running c5 at 300/hr. :surrender I’m giving it a week, and then back to my “fast” script. I’ve made a few decisions

- I’m only working 1-500K. 500k-2M would take months. So 500k-2M is still unclaimed. Sorry but my old/slow hardware limits my productivity up here north of C190.

- Only posting e-scores > 6.0. So far my high was 5.77, which is quite terrible.

- Lastly, I’ve got to play with alternate scripts

Roughly two GPU-days to cover 5-5.35M. Best is 6.37, with four or five polys over 6.0.
I'm using stage1norm near 6e28 (still experimenting for best production), which on my 750ti yields 200+ hits a day with stage2norm= 6e26. I've had a handful of *e25 hits so far, less than ten.

C197
 

The best I've seen is 6.704 through 4.25M.

[QUOTE=VBCurtis;483617]Thanks Max! I'm testing the 1.226 now for best parameters. I'll then use the same parameters to test the other two, will let you know what I chose.[/QUOTE]

The poly with score 1.226 sieved most quickly, and had best yield over most Q (for small Q, the 1.214 had better yield and same sieve speed, but performance fell off more steeply over the likely Q-range).

I haven't tried editing factmsieve.py yet, but assuming I get it to use 134M for all alim/rlim .job files I'll be running 34LP/67mfba-r, alim=rlim=134M. I'll use 16f from Q=3-9M, and 15f from 9M-50M or so. Yield is around 50 for the 16f region, and around 20 for the 15f region. sec/rel is around 0.025 from 3M to 20M, 0.030 on avg from 20-50M. This will be my first full factorization with the f sievers; I will not be sieving composite Q. If duplicate-relation rates are similar to e sievers, this GNFS-179 project will take about the same time as the GNFS-175 I just completed.

15e/33 is forecast to take 50M thread-seconds for 600M raw relations. 15f-16f combo and 34LP is forecast to take 32M thread-seconds for 1100M raw relations.

[QUOTE=RichD;483919]The best I've seen is 6.704 through 4.25M.[/QUOTE]

Best I’ve seen is 6.07! My speed is increasing as I get out of the mud, i.e. c5 < 10^5. Still panning for gold...

Sadly,
