Fast Dynamic Load Balancing Tools for Extreme Scale Systems smithcameron DiamondGerrett ShephardMark S. 2017 Parallel unstructured applications running on the latest petascale systems require partitions optimizing specific balance metrics. Methods combining the most powerful graph based and geometric methods with ParMA diffusive methods directly operating on an unstructured mesh are discussed. The SSE is focused on extending ParMA to support applications with relational structures that can be expressed with a graph structure.
