It turned out that it was the fault of prime95, the default memory set should be friendly for everyone and the PRP tests should be accessible from the menu instead of worktodo.txt only because this problem got me several months ago too. Glad I wasn't the only person. 2 people started the PRP tests without P-1 stage 2, interesting would be if some factors are hidden inside there - https://www.mersenne.org/report_expo...3374113&full=1 If I hadn't encountered these types of problems before, I wouldn't keep asking Kriesel to check whether I have done everything correctly or not.

 2021-04-05, 19:46 #46 tuckerkao   "Tucker Kao" Jan 2020 Head Base M168202123 24×5×11 Posts It'll be nice to have "Show Recommended Tasks before PRP Tests" for every exponent. Then the Mersenne server will show: Trial Factoring from 2^73 to 2^74 Trial Factoring from 2^74 to 2^75 Trial Factoring from 2^75 to 2^76 Trial Factoring from 2^76 to 2^77 Trial Factoring from 2^77 to 2^78 P-1 Factoring with B1 = 1,000,000 and B2 = 40,000,000 Right click on the line to get the assignment. Is it possible to integrate mfaktc-0.21 into Prime95, so the users have the options to choose whether to primarily run the tests from CPU or GPU? Last fiddled with by tuckerkao on 2021-04-05 at 19:48

mfaktc doesn't do prp testing, and P95 shouldn't be used for trial factoring- so there ought not to be a choice to use CPU or GPU. Just use the right tool for each job, you know?

The major disadvantage of mfaktc is that you have to avoid the accidental click on the console window, otherwise the entire factoring progress may become invalid. Prime95 doesn't have this problem.

I can stop Prime95 whenever I desire, so less of the hardware overheating problems.

I'm assuming that the memory sticks will be DDR5 and the monitor resolution will be 2560x1440 or greater.

Trial factoring from 2^78 to 2^79 won't be recommended by GPU72 until M200,000,000+, so I'll stick to the 2^78 ceiling for the M168,000,000+ regions. My ultimate goal is to finish the exponent preparations ahead of the time, so when those exponents transfer to Category 1 or 2, there will only be a binary choice for other users:

1. Poach GPU72 (Trial Factoring reservations up to 5,000,000+ from the current exponent frontier)
2. Perform PRPs on tuckerkao's favorite exponents

Nearly everyone will be able to predict which path Ben Delo's automated machines will advance to.

GPU72 is following the recommended levels as seen on Mersenne.ca. The bit level jump happens between 199.4 and 199.5M

If you have already done the TF work up to the recommended level, GPU72 won't hold onto the exponent. Again, you want other people to do the work of the primality testing for you. We can assume that your parent cleans up after you. The question is just how far that reliance on others to do your dirty work is. ¿ ?

I said *fix* your hardware, not "get new hardware". Other than ignorance, what stops you from fixing your overheating issues on your current machine? You can't buy a $10 case fan or two, or perhaps a new CPU heatsink? What makes you think the next machine you build won't overheat? If you don't know why your current one overheats, how will you avoid the same problem next time? 2021-04-06, 22:23 #53 tuckerkao "Tucker Kao" Jan 2020 Head Base M168202123 24·5·11 Posts Quote:  Originally Posted by VBCurtis I said *fix* your hardware, not "get new hardware".

My CPU has liquid cooling, so it's okay, but that GPU overheating causes mfaktc to frequently quit itself. I'll make sure the liquid cooling wires up for both CPU and GPU next time.

It's impossible to liquid cool my current GPU which means the new hardware is the must.

So, why did you mention about stopping Prime95 then? You make statements, others give you good advice based upon that statement, then you say that you don't need advice about that.
Ignorance is one thing, stupidity is another.

I got Gerbicz error after running Prime95 over a week, so I'll turn off my machine at least once a week for the night. The overheating of CPU won't occur unless I don't turn off my machine at all, so I can accept this reality now. Not desirable, just okay.

I stop Prime95 when I want to play video games like "Cities Skylines".
