I agree, CUDA took a step in the right direction by allowing annotated C++ source to be compiled for the device. As an HPC developer, I'm using the Kokkos C++ library https://github.com/kokkos/kokkos https://github.com/kokkos/kokkos to switch between CUDA, OpenMP, or Serial modes from a single source code.
