Abstract
The present work focuses on the performance analysis of the DG-SEM implementation of the CFD solver CODA. The turbulent Taylor-Green vortex is employed as a simple testcase for scaling behavior, while for a more detailed ode-level performance analysis more granular kernel benchmarks are used. Bottlenecks in the implementation are highlighted and possible solutions proposed.
