Default Can i stop the server from assigning work that is different from my preferred work?

When i communicate end dates with the server, i also get assigned an LL double check because i don't have enough memory. Can i stop this? It could get annoying unreserving the assignments.

You can set your preference for the type or work either in Prime95 (Windows), mprime (Linux), or on the website

https://www.mersenne.org/cpus/
The default is "what makes sense". What have you set that to? What do you want?

What hardware do you have - in particular how much memory? Generally speaking, not much RAM is needed for most tasks, although there are some tasks which benefit from a lot of RAM.

What makes you believe you are getting double-checks because you don't have much memory? I suspect that the default "what makes sense" will often include double-checks. They are significantly faster to do than first time prime tests. I'm doing a double-check of M57906071 now, which will take around 14 hours, which is around a quarter of the time to do a first time prime test, for which exponents are currently around 104 million.

My preferred work in GIMPS is P-1. And I have an image to prove. I want to either: get only P-1 or not get automatic assignments.

Have you completed any P-1 factoring tasks? If so, which one(s)? You did not answer my questions about your hardware.

I don't know the absolute minimum RAM that is needed for P-1 factoring, but I have used a virutal machine on Amazon with only 1 GB of RAM. That completed P-1 factoring okay. But the 2nd stage of P-1 factoring can benefit from a lot of RAM, although it is not necessary to have a lot of RAM.

I believe you can stop getting automatic assignments by setting something which on the Linux program (mprime) is called "Days of work to queue up". It should have a similar or identical name on Prime95. If that is set to 0, the program will not request any additional work from the server.

Prime95 comes with some very good documentation files. Your answer is there.

You should look in the folder where you have put Prime95. That is generally where help files are for programs.
