Hi everybody,  I am just a newbie of OpenMPI and Parallel Computing. Recently, I have got a project at school regarding implementing Record&Replay Mechanism in MPI_Send(), MPI_Recv() and MPI_Barier(). Could you help me with this project? Either theories or ideas or instructions or actual implementations are all appreciated. Thanks   Sincerely, Le , Duy Khanh Cellphone: (+84)958521704 Faculty of Computer Science and Engineering Ho Chi Minh city University of Technology , Viet Nam
