Reduced Vlasov-Maxwell simulations on GPU.



We review two different numerical methods for Vlasov-Maxwell
simulations. The first method is based on a coupling between a
Discontinuous Galerkin (DG) Maxwell solver and a Particle-In-Cell (PIC)
Vlasov solver. The second method only uses a DG approach for the Vlasov
and Maxwell equations. The Vlasov equation is first reduced to a
space-only hyperbolic system. The two numerical methods are implemented
using OpenCL in order to achieve high performance on recent Graphic
Processing Units (GPU).
