My understanding is that only one GPU will be used. The interface to GPUs only permits one GPU to be assigned per process -- if a process switches between GPUs then the current GPU calculation for the process gets reset and discarded.

To control the maximum number of CPUs, see https://www.mathworks.com/help/matlab/ref/maxnumcompthreads.html or create a parpool that is configured for the appropriate number of CPUs.
