Scalability Study of HiFlow3 based on a Fluid Flow Channel Benchmark
AbstractExploiting the compute power of high performance computing clusters efficiently is a key ingredient in order to solve large, fully coupled systems modeled by partial differential equations with high accuracy. We study strong and weak scalability properties of the parallel Finite Element software package HiFlow3 for a challenging instationary 3D fluid flow problem. For this benchmark study, we ran several simulations with up to 10 millions of unknowns using up to 512 cores on the bwGRiD cluster in Karlsruhe. For large problem sizes, the software package showed good characteristics regarding efficiency and speedup.
The Engineering Mathematics and Computing Lab (EMCL), directed by Prof. Dr. Vincent Heuveline, is a research group at the Interdisciplinary Center for Scientific Computing (IWR).
The EMCL Preprint Series contains publications that were accepted for the Preprint Series of the EMCL and are planned to be published in journals, books, etc. soon.
The EMCL Preprint Series was published under the roof of the Karlsruhe Institute of Technology (KIT) until April 30, 2013. As from May 01, 2013 it is published under the roof of Heidelberg University.
