So you just add a parallel keyword to your C code and you've CUDA
capable code ;)? CUDA (which is a great thing) has no unified memory,
the available operations are limited and requires usually a major
overhaul of the used algorithms. If you take care of this, you can take
advantage of CUDA.

OpenMP might have it's use but I consider the impact in the compiler too
big for real use.
