Background execution

Hi guys


with the new reality brought by A12 (Neural Engine) is it possible to execute models in background if do not use GPU?

If that is the case, how to know if GPU will be used or not? I think that models with custom layers are forced or parcially forced to go to GPU.

If this is true and Neural Engine is allowed in backgroud, a possible path is to see if A12 is present and your model do not have custom layers before forcing it to CPU.

Is there an offical link about this? Did not find it yet.


cheers
