Of course the ETA should be nearly zero or equal to zero.

Off by one bug. Fixed next release.

One issue. If you do a manual benchmark then it always offers to use 4 cores and you have to change it each time.

These are my settings:

prime.txt
...
MinBenchFFT=2688
MaxBenchFFT=2688
BenchErrorCheck=0
BenchAllComplex=0
OnlyBench5678=0
BenchCores=3
BenchHyperthreads=1
BenchWorkers=1
AllBench=1
BenchTime=15

local.txt:
...
CoresPerTest=3

I did a complete torture test with no warnings or errors. This was a follow-up to some issues I had because of an incorrect BIOS setting. Prime95 alerted me to something being wrong. "10" v1709 was doing cold reboots. I reset the BIOS to its defaults. There were no more issues.

How is the runtime of PRP compared to LL on the same exponent?
And which should I do, PRP or LL?

PRP adds a little time to testing but is by far more reliable -- not so prone to hardware errors such as those caused by cosmic rays. Run PRP!

I ran a PRP DC which finished recently. No problem there.

The problem is that even though I have selected the cpu to resume TF rather than PRP, it will not stop getting another PRP exponent.

I have to obtain a fresh batch of manual TFs and then unselect the PRP exponent. I then edit the worktodo.ini file, removing the PRP exponent, and adding in the new manually obtained exponents. Then after having restarted Prime95 I do a manual communictation.

Is there somewhere else I have to go to stop Prime95 grabbing another unwanted PRP exponent?

How long did you wait before switching the type of work?

There is a parameter called "DaysOfWork" in the prime.txt file. If it's set to, for example, "3", then three days before the program estimates that it will finish the last assignment in the worktodo file, it will fetch one or more new assignments.

The idea is to store up three day's worth of work ahead of time (in this example), just in case a network interruption or server outage is happening when the final assignment finishes, which would then leave your computer idle and unable to fetch a new assignment.

DaysOfWork is set at 1

Same principle applies. If the program estimates that there are less than 24 hours to go before all the existing assignments in worktodo are completed, it will fetch one or more assignments.

So maybe the question should be: Did P95 fetch the PRP before or after the work preference was changed?

Prime95 · 2017-11-29, 13:22

Go to the mersenne.org web pages. Under the CPUs page make sure the work preference is set properly for that CPU.

The tail of prime.log might indicate what went wrong. At some point it should have sent your new work preference to the server. If so, did this before or after it got those PRP assignments?
