Abstract
DG-FEM computations of Maxwell´s equations in time domain on GPU clusters were presented. DG-FEM discretization incorporates domain decomposition on the element level, which is used for a highly parallel implementation with speedups of more than one order of magnitude. Further work will include double precision accuracy on GPU as well as investigation of scalability and improved exploitation of the GPU performance.
