So Open-MPI is different from OpenMP, isn't it ? as OpenMP is only for the shared memory architecture. I did various tests for the hybrid case( OpenMP and MPI ) for my FDTD(finite difference time domain) calculation and when I use supercomputers[particularly Bull](using 8 nodes and 8 cores in one node), calculation with MPI for all the communication is faster than OpenMP.
