And another more general question: (6) gcc, clang, and nvcc have some OpenMP offloading capabilities which allow to compile code into binaries which can then run on GPUs. Is the code they produce through OpenMP anywhere close to what one gets directly with i.e. opencl?

I don't know, I haven't eplored OpenMP myself.. maybe some day.

Using OpenMP with the GPU may be fine depending on the problem, but you cant explore the full GPU potential. Parallelizing the loops on the GPU may be sufficient, but when it is not you have to dig deeper.
