In the following figures we show strong scalability (i.e. the size of the problem is fixed, the number of nodes/GPUs varies). The examples represent the solution of the pressure problem of standard benchmarks (3D Cavity 27M unknowns and PitzDaily 16M unknowns). Two types of solvers are used – CG with FSAI and CG with PairWise AMG.
