Scalability Analysis and OpenMP Hybridization of a Code for Direct Numerical Simulation of a Real Wing

The project aimed at extending the capabilities of an existing ow solver for Direct Numerical Simulation of turbulent ows. Starting from the scalability analysis of the MPI baseline code, the main goal of the project was to devise a MPI/OpenMP hybridization capable of exploiting the full potential of the current architectures provided in the PRACE framework. The project was very successful, the new hybrid version of the code outperformed the pure MPI version on IBM Blue Gene/Q architecture (FERMI).
