my 122! efforts have been ended by a heat wave and a failed home AC unit. The best I turned up in 3 GPU-days was 3.14e-14. I searched 60-62M, and 18-18.6M.

It'll be 35C here tomorrow and Saturday; After temps return to normal (inside and out) I may resume a search for this number, or just accept that one of the 3.3e-14 candidates also sieves well. I think we're about where we should be for total poly-search effort, and scores aren't disagreeable.

[/code]It seems that at least one of the last two polys (with E score 3.386e-14) should be test-sieving well.
Anyone is willing to check this assumption?

C164_142_95
 

C164_142_95 is a composite stub remaining after yoyo@Home got a p50 hit.

Could anyone help search for a GNFS poly? My GPU rig is currently offline. Thank you in advance.

I got you. Have had to put all CPU-intensive tasks on hold until I get my high temp issue worked out, but this should be fine. The top deg5 coefficient is only ~50M, so I'll just run through the whole thing and see what the best polys are. Then Max can maybe optimize them a bit more.

Thank you. Max is out of town for awhile, but perhaps he can sprinkle some magic on it when he returns. But a few days of GPU time should give great results regardless. [url=http://www.mersenneforum.org/showpost.php?p=457286&postcount=59]The best poly table[/url] gives 9.26e-13 as the best score to date for a C164 but that's just the high water mark.

I re-ran the range with looser Stage 1 and 2 norms. A higher score has popped up:

Is anyone actually sieving 122!+1 ? I didn't see the polynomial-search work here until I was already two GTX1080-days into a GPU run.

I would like to do the sieving myself if nobody else is desperate for it, or I could switch to 145!-1 if someone else is already well into the chase for that fox.
