That said it would be interesting to determine how much total compute was done on 14.0. I'd need access to all P1, PP1, ECM and TF work done by any of us in the last couple years. And even if I had it the cyphering itself would be quite onerous.

Doing TF only would take: 10 more bit levels to 77 bits. Almost 4.4M GhzDays That would be over 2.5 years with a 2080Ti GPU at 4,600 GhzDays/Day. This was probably optimistic because it used the formula from the GIMPS Math page that said Quote:
I am seeing factor rates much lower than that; 1/85 with moderate P1 done and 1/100 with aggressive P1 done.

I have started some factoring work in the 12M range.
To avoid toe stepping, here is what I´m doing: TF: 12.9M to 73 bits. Will take at least 3 months to complete. If/when I stop/finish I´ll let you know. P1: 12.0M. I am still experiencing with the bounds to use, so for the moment I don´t have any estimate for the time to finish. Will keep you posted.

Looking here someone has 12.7, 12.8 and 12.9 all owned to 73 bits.
Unless you reserved all of 12.9 for yourself already it is probably Anonymous. And if so he will have all 3 ranges at 73 bits in about a month.

Have we considered PP1 as a viable alternative to pm1 for low expo?

I'm working in the 6.9M range doing P1 (B1=4M, B2=110M). I have roughly a 2.5% chance of finding a factor per exp.
I got super lucky today and found 4 factors from my last 22 tests! https://www.mersenne.org/report_expo...6975583&full=1 https://www.mersenne.org/report_expo...6908203&full=1 https://www.mersenne.org/report_expo...6907297&full=1 https://www.mersenne.org/report_expo...6906943&full=1 I should find the remaining 11 factors over the next ~9 days.

12.9M et al was taken by our mysterious Anon, reserved through GPU72. Please note GPU72 does not reserve from Primenet for the <2K subproject. That was the reason for the nomenclature change from "Owned" to "Curated" on this report. 12.0M or 12.5M might be of interest to you to work... Please let us know, and either reserve it through the GPU72 interface, or I can "release" it. Your choice. P.S. Sorry for the high bandwidth. I'm juggling a few things...
