Parallel Performance Optimizations on Unstructured Mesh-based Simulations


This paper addresses two key parallelization challenges the unstructured mesh-based ocean modeling code, MPAS-Ocean, which uses a mesh based on Voronoi tessellations: (1) load imbalance across processes, and (2) unstructured data access patterns, that inhibit intraand inter-node performance. Our work analyzes the load imbalance due to naive partitioning of… (More)
