Assignment 4:Point-to-point Communication

(Finding Maximum Value)

Point to Point Communication

Point to point communication is the simplest form of message passing.

A message is sent from sending processor to a receiving processor.

This assignment is about Synchronous communication, which means the communication does not complete until the message has been received.
