I will now work on a second pass of P1 factoring over the 2.8M range. After digging around the forum a little bit more, I found this post that recommended spending 56% of the ECM effort on P1 factoring. Getting the 2.8M range below 2000 unfactored will likely require additional ECM work after this pass of P1 factoring. Last fiddled with by masser on 20191231 at 18:11 Reason: add link

The 2.8M range now has less than 2000 unfactored. I will "unreserve" and move on to the 2.9M range.

2.9M now has less than 2000 unfactored. Pursuing the white whale of 14.0M next...

I probably don't have to tell you that you will need aggressive B1/B2 values. Enjoy. Last fiddled with by petrw1 on 20200404 at 22:15

I have the stage 1 P1 savefiles for the factoring work I completed in the 2.6M, 2.8M and 2.9M ranges.
If someone were interested in further factoring the candidates in those ranges, the savefiles might save them quite a bit of work. I'm certain this has been discussed on the forum in the past, but currently, there is no online repository for savefiles, right? My machine is (slowly) running out of storage space, so I might have to begin deleting the savefiles. It would be nice to have a place to stow them for future interested parties.

I don't have the hard math but I think it would be more efficient to take an exponent with lower/mediocre bounds with no save file as a starting point than my aggressively P1'd exponents with the save file.

The savefiles in the 2.6M range are a lot closer to some of the thorough factoring efforts. I don't know enough about those efforts to understand if the savefiles have any value to anyone. Last fiddled with by masser on 20200523 at 16:57

I have spare storage  before deleting yours, would you mind sending them to me? I could figure out a way to make them publicly availible. How much data are we talking about?

Sure, thanks! Maybe this way we can start a central system.
