What is the maximum number of Process Cards can be used for GPU computing with Parallel Computing Toolbox 5.0 (R2010b)?

What is the maximum number of Process Cards can be used for GPU computing with Parallel Computing Toolbox (R2010b). I have a 4 cores (each core 1 processor) in my 64-bit Windows machine.

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.
