The present work is targeted at performing a strong scaling study of the high-order spectral element fluid dynamics solver Nek5000. Prior studies indicated a recommendable metric for strong scalability from a theoretical viewpoint, which we test here

Hypre, a library for linear algebra, is used to replace a Matlab code for performing the setup step of an Algebraic Multigrid Method (AMG). The AMG method is used to compute part of the preconditioner in Nek5000, a code for Computational Fluid Dynami
