Before revision:  The generated hybrid-parallel (MPI+OpenMP) code is  significantly faster than matrix-based approaches on the node level and performs in accordance with the Roofline model.
After revision:  The generated hybrid-parallel (MPI+OpenMP) code is fully vectorized using Single Instruction Multiple Data (SIMD) extensions. It is significantly faster than matrix-based approaches on the node level and performs in accordance with the Roofline model.
