Since SRBase is the group that will take the advantage on the higher TF depths, it should definitely be the assignments of that group which you've just mentioned they need more works to do. Last fiddled with by tuckerkao on 20210925 at 08:49

I have some cooling problems with my current GPU, it has to rest from time to time, the reason why I want to buy a new machine. Too bad DrKirkby quit GIMPS, he prefers the wavefront exponents and has a lot of memories capable of running large amount of P1 factoring. I'll finish the P1 which shows the details on the attached image below. If no one takes that exponent within a week, I probably won't run more. Last fiddled with by tuckerkao on 20210925 at 09:16

M115173323 has a factor: 64115403008215858576973359
The same FPM1 fate as M168173323, interestingly both have a factor in the 2^80+ bits. I don't need to run TF 2^76 to 2^77, that's almost certain no factor within that bit. Last fiddled with by tuckerkao on 20210925 at 12:48

You obviously haven't been following the discussion in the threads about SRBase's TF work. The plan has been doing breadth first TF. There have been discussion to try to change that to work near the wave front, but that is not in the (GPU)cards.

If I pair it up with Nvidia Geforce 3060 Ti, the total price of the new PC shouldn't be exceed $2000. It'll be nice to have the new DDR5 memories and PCIe5 which shouldn't be less powerful than DrKirkby's machines. Trial factoring of 2^76 to 2^77 of M115M will only take around 1 and half an hour on Nvidia Geforce 3060 Ti. I figured that 2 of such PCs together will generate more total outputs than 1 $4000 AMD Threadripper 5970X PC with Nvidia Geforce 3080 Ti. A lot of things can change during the meantime, I cannot make the final decision until I see the detailed descriptions of the available products. Last fiddled with by tuckerkao on 20210926 at 07:41

M106489771 served as a great example that a factor between 2^76 to 2^77 could be found through P1.
Consider the chance of a P1 finding a new factor is around 4x of a TF from 2^76 to 2^77, however the P1 only takes slightly longer than the TF, as far as I understand that Kriesel is able to finish both of those within an hour and a half. The 4x chance is a reality because digging out new factors between 2^77 to 2^100 have been quite frequent even using the standard bounds. Last fiddled with by tuckerkao on 20211001 at 22:30

UncWilly has been correct, it's better to run P1 on my CPU first while my GPU aiming another exponent, M168607223 has a factor between 2^77 to 2^78 which was found by P1. Running P1 will be able to collect most of the low hanging fruits. If no harvests, then target the TF 1 bit higher than the GPU72 recommended level.
