Specify Multi core performance processor usage

Hi all. Is there a way when using multi core on a PC to specify that Matlab uses the performance cores first before using the efficient ones or is this already in the program? I'm using it for NN training.

Ime in macos it uses the performance cores first, and if you request more cores is starts using the efficient cores. You can check actually which cores are getting utilised, in macos in activity monitor or command line tools like btop.

I'm not sure on the PC.

Is there a reason why you're training on a CPU instead of a GPU?

There are ways to set processor affinity in Windows (that is the keyword you should google), but I am not aware of tools inside Matlab to specify an order.

[Stephen Gray]

Yes, the training function I am using does not run on the GPU. I've tried using a funtion that does run on the GPU but it isn't as accurate as the CPU one.

Thanks! That answers my question.

It seems the general pattern is MATLAB uses performance cores first via native multi-threading, see Alison Eele in this thread
