CUDA 11.6 added the nvcc
-arch=native
flag to automatically compile for the host GPUs architectures.This pull request checks whether the version of nvcc is 11.6 or higher and sets the flag accordingly to either "native" or "all".
Using the "native" flag is highly recommended as it optimizes both the size and performance of the compiled code.
On the other hand, using the "all" flag as fallback, at least ensures that the build can be successful on a wider range of architectures.
If yes -
-arch=native
If no -
-arch=all
