The work group cooperates with Prof. Tim Warburton and Dr. Nico Gödel in parallelizing the open source NUDG++ software, i.e., using the Discontinuous Galerkin method in high frequency electromagnetic field computations on GPUs. Presentations of this work received the Emerald Best Paper Award and a best paper commendation at the 17th Conference on the Computation of Electromagnetic Fields (COMPUMAG), see the list of Publication.

For low-frequency problems the in-house research simulation software "MEQSICO" (Magneto- and Electro-Quasi­static Simulation Code) is used. New features, e.g. parallel assembly or explicit time-integration schemes were developed such that GPU acceleration can be exploited. Finally, for comparison, reference simulation and commercial projects from industry partners the commercial simulation software "CST Studio Suite" is used. We are cooperating closely with the vendor "CST AG" in testing and optimizing new releases of their software on GPU clusters, both available at the CST site and at the Chair of Electromagnetic Theory.

The following GPU-computing hardware is currently available

• a DELL workstation with a NVIDIA Tesla K80 Module is used mainly for simulations of biological organisms using commercial software packages within funded research projects
• a DELL Cluster with 16 NVIDIA Tesla M2090 Modules is used for research and production simulations using commercial software packages within funded research projects
• an additional multi-GPU cluster-based HPC-system from Hewlett-Packard featuring 40 NVIDIA Tesla K20 Modules is used for time-consuming numerical simulations of demanding scenarios
