I did fix a bug that caused the pairing % to exceed 100.

I use Prime95 for years on my personal, and CRUS search. I like all extra checks ,but can I disable generating proof file, since it will use disk space for nothing,and I dont need to upload proff file to no one.
Thanks

Try setting the disk space prime95 is allowed to use to zero.

I think it might be better to change prime pairing format from pair%=xx.xx to pair: xx.xx% so that it's consistent with the rest of the output line.

There seems to be a problem with fetching work in some cases. I have one of my cores set to get P-1 work, while the others do PRP. When one or more of the PRP tests also want to do a P-1 test before starting, only one stage 2 can run at a time. If the P-1 core is blocked from doing stage 2 it will do stage 1 work on the exponents it has, but if it finishes all of them and still cannot start a stage 2 because of another core, it will stop and wait instead of getting some new work to do.

You can increase DaysOfWork in prime.txt (or the equivalent GUI setting).

But looking at the broader picture, it might not be a bad idea in a situation like this, if Prime95 can't find anything else to do while waiting for RAM availability, it could start working on the PRP, on the 95% probability that the P-1 test will not find a factor, rather than leaving idle cycles.

Are the ECM B1 and B2 bounds not allowed to be changed from their nominal settings?

I ´ve been using Build 8, and didn´t have a single problem so far. Today I fetched some manual ECM assignments in the 500k range, and the worktodo lines came with the expected values of 250000 / 25000000 for B1 and B2. I changed them to 500000 and 50000000 and restarted Prime95.The program rejected those lines, giving out the message:"Illegal line in worktodo.txt file: ECM2=blablabla". The lines were not deleted from worktodo.txt, though.

Is this the expected behaviour? I /think/ in previous versions one were able to change the bounds at will.

PRP (and LL) are already coded to do this. I'll see if I can replicate the problem.

This is not the expected behavior.

Default Stable mprime version for the next GPU72 Colab build?

Hey.

So, I've had a few requests to upgrade the mprime build sent out in the Payload.

Since several of us are now being given at least a few hours of compute each day, I'd like to program a day for me to do this (along with some other change requests).

George, your counsel? It will be solely doing P-1'ing; and yes, I know about the non-backward compatibility for stage 2...

I'm modeling next weekend.

30.4 seems stable enough to make the transition. The improved P-1 bounds is worth the effort.
