The documentation for nvcc, the CUDA compiler driver.

CUDA code runs on both the central processing unit (CPU) and graphics processing unit (GPU). NVCC separates these two parts and sends host code (the part of code which will be run on the CPU) to a C compiler like GNU Compiler Collection (GCC) or Intel C++ Compiler (ICC) or Microsoft Visual C++ Compiler, and sends the device code (the part which will run on the GPU) to the GPU. The device code is further compiled by NVCC. NVCC is based on LLVM.

Any source file containing CUDA language extensions (.cu) must be compiled with nvcc.

Nvidia CUDA Compiler (NVCC) is a compiler by Nvidia intended for use with CUDA.

nvidia-smi 和 nvcc --version 显示的 CUDA Version 差异：

• nvcc --version refers to the version of the CUDA toolkit installed on the system. The CUDA toolkit includes the compiler, libraries, and other tools. (NVIDIA Toolkit driver)
• nvidia-smi refers to the CUDA GPU driver version supported by the installed NVIDIA graphics driver. (GPU driver, aka CUDA Driver)

The CUDA driver version must be greater than or equal to the CUDA toolkit version for proper functionality.

4.2.8.23. --list-gpu-code (-code-ls)

List the non-accelerated gpu architectures (sm_XX) supported by the tool and exit.

If both --list-gpu-code and --list-gpu-arch are set, the list is displayed using the same format as the --generate-code value.

4.2.8.24. --list-gpu-arch (-arch-ls)

List the non-accelerated virtual device architectures (compute_XX) supported by the tool and exit.

If both --list-gpu-arch and --list-gpu-code are set, the list is displayed using the same format as the --generate-code value.
