If you can get this to run on your machine, it will surely outperform
any efforts what you can do with a python-CUDA bridge on your own. GPU
programming is hard, and efficient GPU programming is really hard. To
get an impression, this talk shows how some changes to an OpenCL program
can improve the speed by 60x compared to a naive implementation:
