An optimized solver for unsteady transonic aerodynamics and aeroacoustics around wing profiles

Résumé

The extensive optimisation for HPC of Fluid Dynamics software is possible under a variety of aspects on GPU clusters within GPUDirect/C/CUDA/Thrust programming paradigms. In particular, our algorithm could be made more modular to adapt to the CUDA register usage limit, Thrust libraries provide highly efficient solutions on global memory computations and warp collaboration through shared memory proves crucial. Large Eddy Simulation, based on basic principles of field mechanics, despite its very high computing requirements, complements Reynolds-Averaged Navier-Stokes models, which lack versatility. In the field of aeronautical flows around wing profiles in steady or off-design configurations, our solver provides efficient solutions on 128-TESLA clusters for adequate 2-billion cell grids.
