Peta-Scale Hierarchical Hybrid Multigrid Using Hybrid Parallelization

Conference paper
Part of the Lecture Notes in Computer Science book series (LNCS, volume 8353)


In this article we present a performance study of our finite element package Hierarchical Hybrid Grids (HHG) on current European supercomputers. HHG is designed to close the gap between the flexibility of finite elements and the efficiency of geometric multigrid by using a compromise between structured and unstructured grids. A coarse input finite element mesh is refined in a structured way, resulting in semi-structured meshes. Within this article we compare and analyze the efficiencies of the stencil-based code on those clusters.
