Title: added a cuda Exp.

Another pretty simple one... This is just a exp implementation in CUDA. It's actually not that much faster than the CPU version (I have a sneaking suspicion that exp is expensive on the GPU), but it might save you from having to perform a expensive memory transfer. Either way, I think it was missing.
