Yes I realize that 1% is a non issue; I should have mentioned so in my post.

Does 26.2 fix this?

In the 64-bit Linux version, there appears to be something wrong with the calculation for percentage completed during P-1 stage 2. My tests have been outputting saying they are 100% complete for at least a few minutes before the test actually ends. Not a big deal, since the test is still running and eventually finishes, but it may lead people to believe that the test is somehow "stuck".

Doesn't look like it, at least for when it calculates the memory usage (not sure about when it actually uses it). With local.txt like...
Code:
Memory=300
[Worker #1]
Memory=150
[Worker #2]
Memory=125
...they both assume they can have 300 MB. Without the non-worker-specific Memory line, they only assume they can have 8 MB. It's completely ignoring the Worker-specific settings.

I experienced this same issue with the 32-bit Linux build... it was more than the few minutes you mention, but the affected machine for me is a P3 1.4GHz using 1GB of RAM so it's not exactly a speed demon... ;) Same as you, it did eventually complete successfully.

A few minutes was a conservative lower bound because that was as far back as I could check in my terminal =P. I think it might start outputting 100% when stage 2 starts working with the last set of relative primes, but that's just a guess.

This bug has been around for ages. I've never been able to find it. By any chance did you stop and restart during stage 2? Did you change memory settings (or did you get a restart due to a day/night memory changeover)?

Can you email the *.txt files? I'm stepping through the code and it appears to be working for me.

I haven't touched the memory settings since I first installed it, and daytime/nighttime memory settings are the same. It is possible that stage 2 was stopped at some point both times I noticed it occur. I'll try to keep track of how often it occurs, and see if I can recreate it on a test that I run all the way through without stopping.

On further investigation, I've found that it is only on the calculation of optimal bounds that it incorrectly assumes it can have the full amount. When you actually get to the part where it uses the memory, it splits it using the worker-specific settings that are in local.txt.
Nothing in the .txt files are private or sensitive, so I'll just post them here (instead of email). (along with the .txt file I made while investigating to find the above results, it has full raw data - it's not very annotated, but I think it's clear enough)
