Message Passing Interface (MPI
) is a communication protocol
where modules interact by sending messages
to each other through a communication channel
Both Point-to-Point Protocol and collective communication are supported.
Message Passing Interface "is a message-passing Application Programming Interface, together with protocol and semantic specifications for how its features must behave in any implementation."
Message Passing Interface's goals are high performance, scalability, and portability.
Message Passing Interface includes methods of Inter-Process Communication and Application Programming Interface (APIs) for Message queues
