Each MATLAB or worker can access one GPU at a time. Since the Parallel Computing Toolbox currently ships with 8 local workers, you can have each worker accessing one GPU. This means that you can use 8 GPU's on a single computer with PCT.
If you have a cluster running the MATLAB Distributed Computing Server (MDCS) then you can run as many worker's on a machine as you have licenses, and they can each access one GPU; in that situation you can access as many as you like.
