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.

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 [M]M57906071[/M] 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.

Prime95 2021-06-26 01:36

and how much memory is available for prime95 to use?

birtwistlecaleb 2021-06-26 01:49

How can i see that?

[QUOTE=birtwistlecaleb;581927]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.[/QUOTE]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.

Thanks! I currently have 10GB, how much do i need to do S2 P-1 of an exponent between 100,000,000 and 110,000,000?

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

birtwistlecaleb 2021-06-26 02:18

Where are they?

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