Using both a GPU and CPU for parallelization

I am looking to parallelise a dynamic simulation, it has a large amount of simple data to pre-process via lookup tables which I was hoping to do with a GPU before running the actual complex analysis that will require a CPU. Is there any way to set up the pool to use GPU and the a CPU at different points in the code?

Thanks

Class of gpuArray runs on the gpu device.....if not on the cpu...
