Sorry that I didn't make it clear in the original mail. The reason I
talked about CUDA, is to express, that's the one thing I want to get rid
of and replace it with Other free alternatives listed in original mail.
But I need help packaging those free alternatives.

I mentioned it in the original mail. But packaging these thing requires
knowledge for kernel space stuffs, like kernel module for GPU, which I
don't have. So, any help is appreciated.
