Prodigious output Max! Thanks for the polys. You’ve set the high water mark for this composite. Though my plan is to test sieve only those polys with an e-score > 1.4e-13.

I should be done with searching c5 < 1M by the weekend. Planning to take 2-3M after that. Thanks to all for their respective efforts to date.

[QUOTE=VBCurtis;482466]3-5M produced nothing above mid 1.20's. Continuing on to 6M.[/QUOTE]

Thank you for continuing the search. Made one quick/light pass over 2-3M, now making another slow/deep pass which will take a few days. Likewise, I have found nothing worth reporting so far.

Based on the search time spent so far and the very high relative score(s) of the top flares, does it make sense to end the search at 6M? Or is that quitting too early? I’m a relative newb in the poly search game, so I’m open to any guidance.

Either way, thanks to all of you for your efforts. Even if we stopped right now, we’ve advanced the C177 benchmark considerably without ridiculous amounts of GPU time.

FWIW, I’ve got five more GNFS jobs in the pipe. They range from C178 to C182. For another day perhaps.

IMO, setting a record is grounds for proceeding to test-sieve and GGNFS. I'll be stopping at 6M, and I don't think having multiple candidates over 1.45e-13 is in any way under-searched.

I'll have spent about 100 GPU hours, and I assume you two have spent more. 10 GPU-days is a bit light for this size, but Max did a CADO search too and we got great results.

I have a GNFS179 next in my personal queue, and had planned on 14 GPU days minimum (with more if I don't get a score I like). That's consistent with what we did here.
