A NOVEL MASSIVE PARALLEL POSSION SOLVER FOR BEAM DYNAMICS

We present a novel parallel Poisson solver based on semi-unstructured grids, a ﬁnite element discretiza-tion (FEM) of the three dimensional computational domain. Multigrid is used for solving the resulting linearsystem of equations. The code is based on expression templates and written in C++. Results for a bench-marking problem are presented.
