Off by one bug. Fixed next release.

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.

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!

 2017-11-29, 05:33 #105 bayanne     "Tony Gott" Aug 2002 Yell, Shetland, UK 14116 Posts 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? Running 29.4 build 5 on my Mac

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.

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.

 2017-11-29, 13:22 #109 retina Undefined     "The unspeakable one" Jun 2006 My evil lair 5×1,223 Posts So maybe the question should be: Did P95 fetch the PRP before or after the work preference was changed?
 2017-11-29, 13:22 #110 Prime95 P90 years forever!     Aug 2002 Yeehaw, FL 11100111011112 Posts 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?
