Figure 11. Efficiency per newton iteration vs. time for Q2 finite elements. The test used matrix-free Newton–Krylov methods with p-MG preconditioning and BoomerAMG coarse solve. Problem sizes (in MDoF) are annotated for the minimum and maximum sizes for each host and number of nodes combination. The impact of latency was ever-present and memory capacity limited the right end of each curve.
