Ok, I tried it (for as long as my limited free time and interest in CUDA allows). The closest I came to a getting started guide is this [0], which by my (perhaps naive count) is 25561 lines of documentation, and I would probably need to learn more C++ to understand it in detail.

I'm sure CUDA is great, and if I had more free time and/or better reasons to improve the performance of my code it would probably be great for me. My point was mainly that a few lines of code which may be trivial for one person to write may not be for someone else with different experience. Depending on what the code is being used for even a vast increase in performance may not be worth the extra time it takes to implement it.
