A semi-Lagrangian discontinuous Galerkin method for drift-kinetic simulations on GPUs
Lukas Einkemmer, Alexander Moriggl
In this paper, we demonstrate the efficiency of using semi-Lagrangian discontinuous Galerkin methods to solve the drift-kinetic equation using graphic processing units (GPUs). In t…

Semi-Lagrangian 4d, 5d, and 6d kinetic plasma simulation on large scale GPU equipped supercomputer
Lukas Einkemmer, Alexander Moriggl
Running kinetic plasma physics simulations using grid-based solvers is very demanding both in terms of memory as well as computational cost. This is primarily due to the up to six-…
