Would a better example be OpenCL (at least the vision of it)? OpenCL kernels can run on both CPU and GPU, and unlike CUDA, it's not vendor locked. Though I've only really used CUDA, I don't know how comparable OpenCL is these days.
One problem is that although OpenCL can run on both CPU and GPU, OpenCL code that performs well on CPU and OpenCL code that performs well on GPU can be different.
