Software Engineering in Parallel and Distributed Scientific Computing: A Case Study from Industrial Practice |

|---|---|---|
We report on results from an interdisciplinary research project of computer scientists, mechanical engineers and numerical analysts from industry and academia. We have designed and implemented a portable distributed memory parallel version of CFX-TfC, a state of the art computa- tional fluid dynamics simulation software package that fea- tures finite volume discretization on unstructured hybrid grids in combination with an algebraic multigrid solver. Performance results on a number of parallel hardware plat- forms indicate high efficiency and scalability. Systematic application of software engineering methods has been a key contribution to success and helped to avoid bottlenecks found in many other parallel CFD codes. A key module of TfC, the algebraic multigrid solver (AMG), has been re-designed according to the object ori- ented paradigm. The object oriented (OO) AMG solver has been implemented in C++. OO technology has increased the solver's maintainability and readability. Run-time effi- ciency is acceptable (compared to the Fortran 77 version); it could still be improved by applying further optimizations. Since networks of workstations (NOWs) are of particular interest for small and medium enterprises (SMEs), we have implemented a resource manager that allows PVM applica- tions such as Par-CFX-TfC to be executed in batch mode without interfering with interactive users. The resource manager features transparent checkpointing and process migration. |
