I’ve been wondering what happens on older graphics cards in regards to the CUDA Driver API.
Some functions have a conditional in front of them, I am not sure what it means:
#if __CUDA_API_VERSION >= 4000
What happens on older graphics cards ? Will these functions fail ? Will these functions not be present ?
What if users install new drivers, will these functions be available again ?
For example cuStreamDestroy has such a conditional…
