5.1.2 MPI 's Support for Libraries

The corresponding concepts that MPI provides, specifically to support robust libraries, are as follows: Communicators (see [16,24,27]) encapsulate all of these ideas in order to provide the appropriate scope for all communication operations in MPI . Communicators are divided into two kinds: intra-communicators for operations within a single group of processes, and inter-communicators, for point-to-point communication between two groups of processes.
