Int MPI_Finalize (void)
It ends the MPI environment. Any MPI function cannot be called after MPI_Finalize. Each MPI process belongs to one or more groups (which are also known as communicator).

Additional groups can be produced by the user as and when needed. Now we will learn a number of functions related to communicators.
