There was an m122582657 file remaining, which I moved to a large memory system for stage 2, which indicated it could do 480 relative primes in one pass. I then investigated further on the 6GB system. It turns out that in prime95, v30.3b2, fresh install on a newly built system, Options, Resource Limits, Advanced, Daytime and Nighttime P-1/ECM memory limits had defaulted to 0 GB. Other systems had had earlier versions of prime95 upgraded to v30.3b2 and probably already had enlarged P-1 memory limit values in prime.txt.

Yes, this is the issue I mentioned in #58. Hopefully it will be fixed soon in later versions, as the default will be raised to 256MB (#63).

I had to move the CERT work manually to the top, otherwise it would not have been completed for a few more weeks until my other test finishes.

Thanks for the CERT of my PRP Run.

You do not need to re-arrange your worktodo.txt file. Cert work will get done quickly regardless of where it appears in the file.

Not an issue, manual or otherwise. https://www.mersenneforum.org/showpo...&postcount=181

Only if an attempt is made to submit such work without having a valid assignment ID.

The test options in the Advanced menu may be a holdover from another time and not given much attention now. Sometimes, as a programmer, it is simply better to leave something of this type in a complex program rather than try to remove it.

I confirmed one of my own results as well, different machines though.

Sum-input-output checking was removed because no one uses it. Optimizations made for AVX and later FFTs made this error check impossible. If you have a Pentium 4 or maybe some of the early Core/Core2 CPUs, then you could get the sum-input error checking.

All the code is still there, only the menu choice is gone. That is, you can activate the error checking on ancient CPUs by editing prime.txt.
