In this paper we present selected ongoing computations, performed on HLRS clusters. Three efficient explicit Discontinuous Galerkin schemes, suitable for high performance calculations, are employed to perform direct numerical simulations of isotropic turbulence and turbulent channel flow, large eddy simulations of cavity-flows as well as hybrid simulations of aeroacoustic phenomena. The computations were performed on hundreds to thousands computer cores.
