Figure 12. Preconditioner setup efficiency spectrum for using matrix-free Newton-Krylov with p-MG preconditioning and BoomerAMG coarse solve. The times and efficiencies are per newton iteration. Problem sizes (in MDoF) are annotated for the minimum and maximum sizes for each host and number of nodes combination.
