Abstract

This paper presents two algorithms solving the load balancing problem arising in a data parallel implementation of multigrid methods on unstructured, locally refined meshes. The differences between additive and multiplicative multigrid and their influence on the load balancing procedure are discussed in detail. The quality of the proposed algorithms is assessed by numerical experiments on several parallel computers.
