Unfortunately, 10 tests_saved is the maximum. This is usually not enough. A few data points:
Code:
[Work thread Dec 10 09:58] Assuming no factors below 2^64 and 10 primality tests saved if a factor is found. [Work thread Dec 10 09:58] Optimal bounds are B1=554000, B2=33719000 [Work thread Dec 10 09:58] Chance of finding a factor is an estimated 9.14% [Work thread Dec 10 10:01] Assuming no factors below 2^74 and 10 primality tests saved if a factor is found. [Work thread Dec 10 10:01] Optimal bounds are B1=358000, B2=14042000 [Work thread Dec 10 10:01] Chance of finding a factor is an estimated 2.91%

Good idea. This is the right way for our purpose.

Can the GPU72 colab sessions get upgraded to v30.7 at least?

OK, I tried a hack. Prime95 ought to now register these as PM1S (same as a Pfactor assignment). I assume they have the same expiration rules (I don't know what they are). You cannot get P1 assignments from the server. Hope that helps (and works).

It's a bit complicated...
Whenever there is an incompatibility between versions of mprime I have to do some work to ensure "sane transition" of the checkpoint files. It's a bad Cx when someone loses a large amount of compute. @George... Thanks for the alpha hack on Primenet accepting PM1S via the API. I'll test and "sniff the wire" over the weekend on this. Just to share... Few appreciate just how well this collaborative, multidisciplinary, and agile adhock team works. I sometimes present this as an example of what /should/ be standard MO. When I do this, many people run away with their eyes closed and their hands over their ears... Seriously. Last fiddled with by chalsall on 20211210 at 23:11 Reason: s/stiff the wire/sniff the wire/; # Very different things...

Looking ahead to below 20M
2xM is about 3 months from complete ... holy carp is the new P1 fast!!!!
So I'm looking ahead to 1xM and under: With TF getting less efficient as the ranges get lower and P1 more efficient and so bloody fast now the balance of power is changing. I'm not sure the TF'ers can keep up to the P1'ers going forward barring a big TF farm surfacing soon. I can't predict the balance of TF vs. P1 going forward but if I use my farm as a *rough* gauge:  My PC farm of 5 will be able to clear about 10 P1 factors a day or a range with 70 ToGo in 1 week.  My 2 GPUs would need more than a month to advance 1 range to 73 bits and 2+ months to 74 bits. I've noticed that recently the bulk of TF work below 20M has been in ranges with less than 50 ToGo. I'd like to encourage the TFers to instead focus their efforts on the *worst* ranges. And to encourage P1'ers to take ranges with the least ToGo and we'll meet in the middle. I think there is a reasonable chance this project comes to an end in 2022. I wish I could say the same for Covid19. Thanks for your time and consideration. And for everyone's help to date.

26.5M is in it's final moments and I don't like to see Code:
Ranges remaining: 100 or more: 9
