Abstract

This work presents a first performance analysis of the software framework UG4 on the Hawk Apollo supercomputer. The software demonstrated excellent scaling properties before. It has now been demonstrated that this also holds true for HLRS’s new flagship and its architecture. Three aspects are emphasized: (i) classic weak scaling of a multi-grid solver for the Poisson equation, (ii) strong scaling for the heat equation using multi-grid-in-time, and (iii) application to a thermo-haline-flow problem in a fully-coupled fashion.
