27th International Conference on Parallel Computational Fluid Dynamics Parallel CFD2015 DEVELOPING A FUTURE-PROOF CFD CODE

Abstract. The future-proof development of a compressible finite-volume RANS code is considered. An existing domain-decomposed Fortran 90/MPI production application has been redeveloped in C including a generic data communication harness, to allow exploitation of diverse hardware platforms, and future-proof the code for new highly-parallel hardware and languages. This includes development of a kernel stencil DSL and source-to-source translation for the auto generation of OpenMP, MPI, OpenCL, and CUDA code versions, and heterogeneous combinations thereof.
