Compilation - NVCC

Any source file containing CUDA language extensions must be compiled with NVCC

NVCC is a compiler driver - works by invoking all the necessary tools and compilers like cudacc, g++, cl, ...

NVCC outpus:

• C code (host CPU code) - must be compiled with the rest of the application using another tool

• PTX (Parallel Thread eXecution) - object code directly or PTX source - interpreted at runtime

• .cu code split: host (gcc) and device (ptx/cubin)

• cubin objects: executed by CUDA driver API directly, linked together with host executable and launches as kernels

• C++ code support: host - full; device - subset;
