How to retire one core in a dual-core CPU?

Rodrigo · 2011-07-29, 16:33

Hello,

Suppose that I have a dual-core Pentium doing work on both cores, and I want to retire one of the cores. Is there a way to do that in Prime95?

I know that you can go Test --> Stop and then select the worker you want to stop, but this leaves the current exponent hanging till PrimeNet reclaims it and assigns it to somebody else. So, would I then go into Advanced --> Unreserve Exponent and enter the exponent for the core being retired? Or is there a different process altogether?

Just want to make sure I'd be doing it right.

Thanks!

Rodrigo

P.S. I couldn't decide if this thread belongs here (because it has to do with PrimeNet assignments) or in the Software sub-forum (because it has to do with Prime95 settings).

I would suggest that you use James H.'s work balancer:

Select that you want to "Split across" 1 CPU. This will allow you to keep the work that you have completed so far and then finish it.

Very cool! I suppose that it would finish all current work, and then pick up new work as normal on the one core.

There's no end to the neat apps that folks have created for the Mersenne prime hunt.

Thanks, Uncwilly (and James!).

Also go to Test/Worker windows, and reduce the number of workers to 1.

Good point -- thanks for the reminder.
