Hmm, yes, I see the previous PRP tests on 2017-10-18 had bad (duplicated) factors. And that seems to be preventing a new test from being run with the correct factors.

but here q^2 doesn't divide

And our hopes of a new Wieferich prime are dashed. 😭

Two problems on M2207441.
1) Somehow the factor got added to the database .003 seconds apart.
2) Somehow a PRP test was run with the doubled factor without triggering the "xxx does not divide Myyy" error.
Database fixed manually.

Does the database test divisibility of each factor into M2207441 individually or divisibility into M2207441/alreadytestedfactors. In the former case the double factor would be permitted.

https://mersenne.org/M2233019 also have a double factor in a previous PRP test.

I have experienced forced restarts while running ECM's on 29.4. I tried 29.3. Same thing. I tried a lot of different things, like resetting my BIOS to its default values. Nothing helped. So, last night, I deleted prime.txt and local.txt. I let 29.4 recreate them. The system ran overnight without incident.

It is true that I added a few things i saw in undoc.txt. The only thing major I added was an Affinity setting to pick specific CPU threads in local.txt. It was as below:

[Worker #1]
Affinity=1,{3,5,7}

I had kept the two configuration files for a long time and simply replaced the program file(s) as they came along. There must have been some kind of hold-over from a version previous to 29.1. As to exactly what that was, I have no idea. I am not sure this was even the cause. So, I will leave the two files as is and see what happens.

There may still be a problem with M2207441 because the newly submitted result by ATH with the correct set of factors shows up as Verified (Factored) rather than Unverified.

I will run the exponent and see what happens.

I would like to know why in v27.9 build 1 AVX recommended by Gigabyte with 5GHZ in the 7700k with 1.38v 2 hours of test and v29.4 build 5 FMA3 does not go through 5 minutes? Bug?

Move the included libgmp.10.dylib to /usr/local/lib/libgmp.10.dylib

I'm working on a better solution.

If by "bug" you mean "evidence my overclock is not fully stable", then yes. Turn speed down, find software runs fine, conclude it's not the software at fault.

That works like a charm. Thanks!

The only way I found stability was by using avx offset -2, some manufacturers do not recommend testing with the prime FMA3 just the old 27.9 with AVX.
