''' Nvidia CUDA Compiler''' ('''NVCC''') is a [[proprietary software|proprietary]] [[compiler]] by [[Nvidia]] intended for use with [[CUDA]]. CUDA code runs on both the [[CPU]] and [[GPU]]. NVCC separates these two parts and sends host code (the part of code which will be run on the [[CPU]]) to a [[C (programming language)|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]].<ref>{{cite web|title=CUDA LLVM Compiler|url=https://developer.nvidia.com/cuda-llvm-compiler|publisher=NVIDIA Corporation|accessdate=Apr 6, 2016}}</ref> According to Nvidia provided documentation, nvcc in version 7.0 supports many language constructs that are defined by the [[C++11]] standard and a few [[C99]] features as well. In version 9.0 several more constructs from the [[C++14]] standard are supported.<ref>https://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html#c-cplusplus-language-support</ref>
Any source file containing CUDA language extensions (.cu) must be compiled with nvcc. NVCC is a compiler driver which works by invoking all the necessary tools and compilers like cudacc, g++, cl, etc. NVCC can output either C code (CPU Code) that must then be compiled with the rest of the application using another tool or PTX or object code directly. An executable with CUDA code requires: the CUDA core library (cuda) and the CUDA runtime library (cudart).
