| Abstract | Partitioning unstructured meshes for parallel adaptive workflows running on leader- ship class systems requires the application of scalable partitioning tools that meet the needs of each workflow step. The combination of the (hyper)graph methods with two criteria partition improve- ment to hundreds of thousands of cores was previously presented [23, 51]. This work generalizes the partition improvement to multiple criteria and presents results to more than one million cores of Mira BlueGene/Q on meshes with over 12 billion elements. |
