Mpi tutorial. ns-3. Models. 21. MPI for Distributed Simulation ¶. Parallel and distributed discrete event simulation allows the execution of a single simulation program on multiple processors. By splitting up the simulation into logical processes, LPs, each LP can be executed by a different processor. This simulation methodology enables very large-scale ...

MPI keeps an ID for each communicator internally to prevent the mixups. The group is a little simpler to understand since it is just the set of all processes in the communicator. For MPI_COMM_WORLD, this is all of the processes that were started by mpiexec. For other communicators, the group will be different.
