Yes, true. But let's be less vague and put a figure on that. We expect something on the order of 99.99...% sureness that it will be prime. The actual figure is unknown, but empirically we see such outcomes.

Yes, it would be a bigger discovery to find a PRP that was not prime at these sizes than finding the next Mersenne Prime.
But I just wanted to stress that PRP test cannot prove primes but Prime95/mprime can with the LL tests.

Was, with permission, with caveats. No support. Not compatible with proof V2 such as produced by gpuowl V7.2. See #4 of https://www.mersenneforum.org/showpo...0&postcount=26

upgrade surprise  p95v303b6.linux64.tar.gz
Recently upgraded to version 3.03b. Yesterday I started my first new exponent under the new version.
This morning I discovered my nightly backup had doubled in size! Checking it I found that I had a new file, p101509819.residues that was 3.1G. That was a big surprise and totally unexpected. While this did not cause me any problems since I quickly found what had occurred, I think a warning would be a good idea when switching to this version. I don't know how big the residue files may be and while I have many TB of storage, a change of this magnitude in the wrong location could have been problematical for someone. https://www.mersenneforum.org/mozex...rmarker1.png

prime95 disk requirements for prp & proof https://www.mersenneforum.org/showpo...&postcount=242 https://www.mersenneforum.org/showpo...&postcount=243 At the very top of mprime/prime95 v30's Whatsnew.txt: Code:
New features in Version 30.1/30.2/30.3 of prime95.exe  1) PRP proofs. This allows GIMPS to doublecheck a PRP test at less than 1% of the cost of a full PRP test! PRP proofs require lots of temporary disk space. See readme.txt for details. PRP proofs require uploading a large proof file. See readme.txt for details. PRP proof verifications require downloading a modest verification file. See readme.txt for details. It seems to me very well documented. Last fiddled with by kriesel on 20201215 at 00:41

That link got mixed up with some Chromium extension on his side (I guess) and thus is invalid.
Yes. If you are always reading path notes etc., then you surely will know about the storage requirements. But: Not everybody will read the documentation. Nonetheless, the V30OptionsConverted option in prime.txt could be used to show a message box to the user when he upgrades, once. This way, the user is not forced into anything and is not surprised. I'm not sure if showing the resource settings is enough to make the point clear to everyone.
