Abstract

Exploiting the compute power of high performance computing clusters efficiently is a key ingredient in order to solve large, fully coupled systems modeled by partial differential equations with high accuracy. We study strong and weak scalability properties of the parallel Finite Element software package HiFlow3 for a challenging instationary 3D fluid flow problem. For this benchmark study, we ran several simulations with up to 10 millions of unknowns using up to 512 cores on the bwGRiD cluster in Karlsruhe. For large problem sizes, the software package showed good characteristics regarding efficiency and speedup.
