We describe work performed inside the elsA ( block-structured CFD software to analyse and improve parallel computation efficiency. Details of MPI implementation are discussed. Computational results are given for realistic industrial configurations (28 106 mesh points) on several massively parallel platforms up to 1024 processors.
