Default host compiler used by nvcc for linux

Question

I am using CUDA 4.0 on Ubuntu 10.10 with GTX 570 (compute capcability 2.0), with the GCC compiler suite. As I understand it, during compilation the CUDA compiler driver nvc

Answer 1

You want the -ccbin option for nvcc, e.g. to use icpc (the Intel C++ compiler), use nvcc -ccbin=icpc (assuming the icpc is available in your $PATH).

Note that you should always pass a C++ compiler (g++, icpc, etc.), since nvcc treats the code as C++, even when it's C code.

Answer 2

AFAIK it uses g++ (to be more precise it uses gcc with language set to c++) and of course g++ for final linking. Run nvcc with --verbose option to see more detail if you want.
