Accelerating shape optimizing load balancing for parallel FEM simulations by algebraic multigrid

We propose a load balancing heuristic for parallel adaptive finite element method (FEM) simulations. In contrast to most existing approaches, the heuristic focuses on good partition shapes rather than on minimizing the classical edge-cut metric. By applying Algebraic Multigrid (AMG), we are able to speed up the two most time consuming calculations of the approach while maintaining its large amount of natural parallelism.
