Linux for Engineering and IT applications

Message Passing Interface (MPI) MPI is the standard of programming parallel applications using message passing. Processes run on network distributed hosts and communicate by exchanging messages. A community of communicating processes is called a Communicator. The default communicator is called MPI_COMM_WORLD. Inside a communicator, each process is attributed a "process ID", called rank.
