Publisher Summary This chapter introduces a Portable Parallelization of the cell-centered Navier-Stokes solver NSFLEX. This solver has been validated for many generic bodies and complex geometries in the range from subsonic to hypersonic flow field conditions. The portable parallelization is part of the German program portable parallelization of industrial aerodynamic applications (POPINDA). The concept of parallelization ensures comfortable handling of the mastercodes. The chapter describes the concept of the communications library for industrial codes (CLIC) and its major tasks. The concept of the communications library aims for a high level of portability to make parallel platforms ranging from workstation clusters up to massively parallelized systems available for production codes. Algorithmic investigations show the influence of massively domain decomposited grids on the convergence behavior of the solver. The chapter presents the results for speedup on different parallel systems showing superlinear scaling on cached platforms. The parallel codes being developed are based on highly efficient numerical algorithms, which allow more accurate simulations and meet increased economic, ecological, and technical requirements. |
