CUDA compiler (nvcc) macro

Question

Is there a #define compiler (nvcc) macro of CUDA which I can use? (Like _WIN32 for Windows and so on.)

I need this for header code that will be common between nvcc and VC++ compilers. I know I can go ahead and define my own and pass it as an argument to the nvcc compiler (-D), but it would be great if there is one already defined.

Answer 1

__CUDACC__

I don't think it will be that trivial. Check the following thread

Answer 2

I know it has been long time now, but you might also find __CUDA_ARCH__ useful.
