How to convert c to c for cuda?

Answer 1

Cuda is c, just using a special library. It is almost identical to standard C, except for the additional options, libraries, and thread handling. Nvidia has a good tutorial. There is a huge difference though. Cuda is basically a large number of slow, memory limited threads, that combined can be much faster than a cpu. Often you will need to rewrite the math algorithm to be highly parallel, and use little memory. AKA, this is going to require some reading and research, it is not as trivial as you would like in many cases.
