--- Comment #1 from Tom de Vries <vries at gcc dot gnu.org> --- Hmm, reading about it a bit more, it's more about enabling algorithms that were not possible before, than about performance improvements. So, we should aim at having test-cases, both openacc and openmp that hang on previous architectures but pass with sm_70+.
