Question

Discuss in details the communication primitives models

Answer 1

Answer:

Message passing is one form of communication

between two processes

A physical copy of the message

is sent from one process to the other

"In the message passing model, several processes run in parallel and communicate with one another by sending and receiving messages. The processes do not have access to shared memory."

(Leopol01)

Message Passing Primitive Commands

SEND (msg, dest)

RECEIVE (src, buffer)

This is a low-level approach to IPC,

and puts the burden of communication on the programmer

Message passing is the basis of MPI (Message Passing Interface)

and PVM (Parallel Virtual Machine)

both of which have libraries

of message passing commands
