Results in terms of scalability were not so good. Thus, the porting and the analysis of the hybrid version (using “mini-apps”) on many core architectures (e.g. Xeon Phi) is needed, before extending the hybrid OpenMP/MPI approach to the entire code, in order to justify the effort of the development. This analysis is carrying out in 2015. The extension of the hybrid implementation on the entire code will depend on the results of this analysis. 2. analysis of scalability improvement using MPI3 new communications (e.g. collective neighbours communications), instead of point to point communications              [[BR]]                '''                    Science Reviewer:'''                                                            [[BR]]                                                            '''                    System Reviewer:'''                                                            [[BR]]                                                            '''                    Deadline:'''                    [[BR]]                                                            '''                    Priority:'''     HIGH               [[BR]]                                                            '''                    Depends on:'''    results of the same action in 2015             [[BR]]                                                            '''                    Principal Investigator : '''   Silvia Mocavero
