ATH 2021-10-03 15:16

It got stuck running benchmark this morning at 5am. "Pausing worker to run the needed benchmarks". It was doing P+1 on 31M (1600K FMA3) with 1 worker 8 cores. Prime95 30.7b1 on Windows 10.

Now 11 hours later when I checked the computer, Prime95 was still using 1 core for something in Task Manager but never ran any benchmarks and no P+1 since 5am. It could not be shut down, had to kill the process in Task Manager.

The file "results.bench.txt" was not updated, I'll see if it happens again tomorrow.

Could it be because it is an old long "results.bench.txt" file at 383 KB going back to April 2019 ?

A line of code mysteriously disappeared. I'll upload fixed executables today.

[QUOTE=Prime95;589305]A line of code mysteriously disappeared.[/QUOTE]

Actually, not a mystery. My text editor begins most commands with ^X (e.g. save file is ^X^S). MS Visual Studio treats ^X as delete the current line. If you then build an executable, Visual Studio saves the file.

I usually catch these fat fingered moments, but this one slipped through undetected. I've taken this moment to change Visual Studio to not map ^X to any commands.

This behavior did not change to my knowledge. Either don't merge the comm and worker window output or go to Test/Primenet/Connection and turn off "Output debug info to prime.log" (a.k.a. Debug=0 in the [PrimeNet] section of prime.txt).

No CERTS
 
I haven't received any CERTS since updating. I have the box "Get occasional proof certification work" checked. Maybe just a coincidence but I usually get several CERTs a day.

Prime95 2021-10-03 23:50

Build 2 with the benchmark fix now ready.

[QUOTE=Prime95;589236]In preferences, set output iterations low -- like 10000.[/QUOTE]

Before running the test, I forgot to change that value (it was 250000). I hope that's okay either way?

CPU: AMD 3800X (Zen 2)
1 Worker, 8 Threads
106M exponent, 5760K FFT
Stage 1: 1100-1120 seconds per output
Stage 2: 1965-1985 seconds per output

I probably should mention that I have Brent-Suyama activated in prime.txt (largely because of personal preference) and that I have doubled tests_saved, is it still helpful or should I run one exponent with default settings?

After updating to build 2 I am receiving CERTS again.

That's OK, thanks for the data.

Brent-Suyama is no longer supported. An artifact of the P+1-style stage 2.

Coincidence.
