Can you elaborate on that? We have the following cases:

1. Only CUDA Fortran
2. Only OpenACC
3. CUDA Fortran + OpenACC together

The only difference I can guess is the CUDA runtime vs. the CUDA driver. The 1st and 3rd use the CUDA runtime, and the 2nd uses the CUDA driver. I might be wrong here. Is that why you need to know the programming model?
