Nested Parallelization of the Flow Solver TFS Using the ParaWise Parallelization Environment

Abstract

The Navier-Stokes Solver TFS developed by the Institute of Aerodynamics of the RWTH Aachen University is currently used in a multidisciplinary project to simulate the air flow through the human nose. In order to reduce the runtime of the expensive computations the ParaWise/CAPO automatic parallelization environment has been used to assist in the nested OpenMP parallelization of the TFS multi-block code targeted at SunMicrosystems shared memory parallel systems. Fur- ther manual tuning improved the scalability of the OpenMP approach.
