Abstract. Parallel multigrid methods are very prominent tools for solv-ing huge systems of (non-)linear equations arising from the discretisa-tion of PDEs, as for instance in Computational Fluid Dynamics (CFD). The superiority of multigrid methods in regard of numerical complexity mainly stands and falls with the smoothing algorithms (‘smoother’) used. Since the inherent highly recursive character of many global smoothers (SOR, ILU) often impedes a direct parallelisation, the application of block smoothers is an alternative. However, due to the weakened re-cursive character, the resulting parallel efficiency may decrease in com-parison to the sequential performance, due to a weaker total numerical efficiency. Within this paper, we show the ...
