I increased the P1 memory resources up to 170 GB, and requested a P1 test as a manual assignment
PFactor=xxxxxxxxxxxx,1,2,103747177,1,76,2 Code:
[Worker #1 May 5 10:20] M103747177 stage 1 is 9.05% complete. Time: 203.402 sec. [Worker #1 May 5 10:20] M103747177 stage 1 is 9.05% complete. Time: 203.402 sec. [Worker #1 May 5 10:20] M103747177 stage 1 is 9.05% complete. Time: 203.402 sec. What does the 203.402 ms means? Dave Last fiddled with by drkirkby on 20210505 at 09:28

Stage 1 of P1 actually needs very little memory. Stage 2 is where the RAM usage will be much more.
203.402 seconds (!) is the time it took since the last status update. That way you can estimate the ETA of stage 1. I'm only wondering why the message is there three times; that should not be the case. P1 can be quite satisfying: Having "success" is much more common than when doing PRP/LL, i.e. finding a factor and maybe even finding a top 100 factor.

Why do you think AMD has no problems with miners? If an AMD card comes along that is very useful for we mathematicians, why wouldn't it also be very useful for mining?

https://blogs.nvidia.com/blog/2021/02/18/geforcecmp/ where Nvidia state the GeForce RTX 3060 software drivers are designed to detect specific attributes of the Ethereum cryptocurrency mining algorithm, and limit the hash rate, or cryptocurrency mining efficiency, by around 50 percent. They want gamers to have the card  not crypto miners. Where would prime hunters fall? It's not gaming, but neither is it mining. It might be a game of catandmouse, with a challenge to miner developers to use the card, without it being detected as mining. Last fiddled with by drkirkby on 20210529 at 19:55

I hope Intel Corei9 12900k can be released as soon as possible  Nov 2021 the earlier possible, so at least a competitive rival stands next to AMD Threadripper 5970X, thus the price won't be too expensive for both.

The leaked Cinebench score seems too good to be true for the 12900k, at least my expectation of the LITTLE in big.LITTLE is that it would not be so performant. I guess removing AVX512 and SMT does make quite a large difference to the die size of the LITTLE. In any case, unless DDR5 speeds ramp very quickly the 12900k (dual channel ddr5?) should sit somewhere between the 5950X (dual channel DDR4) and 5970X (quad channel DDR4) for Prime95. Another question mark is if AVX512 and all 16 cores can be used simultaneously, it's my understanding that windows at least in its current state cannot and I don't know about Linux. Maybe pinning to the rescue?

@drkirby:
I believe once you get beyond 5001000 memory buffers in stage 2, you get rapidly diminishing returns, as the stage 2 primepairing percentage approaches 100%. Do your mprime logs list #bufs and pairing %? Suggest you compare the for several different "how much mem" settings.
