Reduced Vlasov-Maxwell modeling

— We describe CLAC (Conservation Laws Approximation on many Cores), a generic Discontinuous Galerkin (DG) solver for three-dimensional electromagnetic simulations. The solver runs on clusters of GPUs, it is based on hybrid parallelism using the OpenCL and MPI libraries. We explain how to solve the Vlasov-Maxwell equations with this tool. We present several numerical results.
