Intercommunicators are Communicators that contain two disjoint groups of processes, call them A and B. Any process in group A can send a message to or receive a message from any process in group B, and vice-versa. However, there is no way to use an intercommunicator to send messages among the processes within a group. Intercommunicators are often useful in large MPI applications that tie together many, smaller modules. Typically, each module will have its own intracommunicators and the modules will interact with each other via intercommunicators.
