Let's Optimize P-1 for low exponents. TL;DR in post #1. More in posts 60 and 61. - Page 18

alpertron · 2022-08-16, 13:38

I finished the ranges 17.6M and 17.8M. Now they have 4000 exponents with known factors.

I will continue with the range 17.1M.

Prime95 · 2022-08-24, 05:12

Please reserve .06 range (M60000 - M70000). Thanks.

prism019 · 2022-08-25, 03:52

I'd like to work on cleaning up 4.9M.

Sounds good - I'd like to note that I am still working on 4.96M (albeit slowly), so if you could avoid those that would be great. I think it was removed from the first page because I didn't find a factor in the last month.

Will do. I've been working from 4.998 back, so I'll keep an eye out.

I would like to reserve 1.6M please

Sorry. I forgot to run stage 2 on my stage 1 files. May I reserve this again? First results really soon...

For exponents under 20M:
613 total new factors found (includes TF and ECM)
6,525 exponents on my "worthy" list P-1'd since August 1
591 of these were factored... almost 10% success rate.
Just over 244,000 remaining to "deep" P-1

Deeper TF of low exponents (under 50M):
Exponents above 35.6M at 73 bits
Exponents above 22.5M at 72 bits

Awesome!

I'll be away for 6 weeks; so there may not be an October update.
While I'm gone I'm hoping my farm completes most of 5.2, 5.3, 5.5, 5.6 and 5.7M

@Wayne (or other administrators). linament says that he has completed 8.8M, but the list in post #1 has not been updated yet.

Got it, thanks for letting us know.

Thanks

I also checked all the ranges to check for and record activity since August 1
