Processes don't share data, so you can completely forget about grabbing locks, etc. when programming for MPI. This makes reasoning about your source code much simpler.In MPI, it’s easy to get the group of processes in a communicator with the API call, MPI_Comm_group. MPI_Comm_group( MPI_Comm comm, MPI_Group* group) As mentioned above, a communicator contains a context, or ID, and a group. Calling MPI_Comm_group gets a reference to that group object. The group object works the …
