The first argument is an MPI communicator (of type MPI.Comm). An MPI communicator is an object associated with a group of processes that can communicate with each other, and it defines the environment for performing communication within this group. The default communicator is MPI COMM WORLD, which encompasses all processes. The MPi Comm size function determines the size of the associated communicator, that is, the number of processes... [Pg.182]
