MATLAB: I have 4 cores + CUDA supported graphics card. Is this equivalent to 5 cores

Question

Hello

I want to maximize my computer's resources for using parallel computing, probably using spmd. I have 4 cores and a CUDA-supported graphics card, through gpuArray. Does this mean that I can use 5 cores, or does the gpu also require a core from the start?

If this is equivalent to 5 cores, how can I use these?

Thank you

No, the kinds of computations that a GPU can do is different from a CPU, and therefore it cannot function like an additional CPU core. The GPU actually contains many hundred cores of its own, but these cores are specialized, capable of only very simple operations. You can only use the graphics card in conjunction with gpuArray.
