It also wouldn't likely be helpful... To be able to use a GPU
effectively, last I looked, you need to be able to move a large
chunk of data to the GPU's memory, operate on it, and then bulk
move the results back because the cost of moving data between main
memory and GPU memory is very high.

Agreed.
