Message Passing Models
Message passing models are a programming paradigm in which processes communicate with each other through the exchange of messages. This approach enables multiple processes to operate concurrently, with each process responsible for sending and receiving messages only when needed.
MPI Programming
MPI (Message Passing Interface) is a widely used message passing library for parallel programming. MPI provides mechanisms for processes to synchronize access to shared memory, reduce communication overhead, and implement distributed data structures.
Key Features of Message Passing Models:
Processes communicate through messages instead of direct communication.
Messages are exchanged between processes on a need-basis.
Processes share memory through shared data structures.
Messages are used to synchronize access to shared resources.
Advantages of Message Passing Models:
Reduced communication overhead.
Fine-grained control over message communication.
Support for distributed systems.
Disadvantages of Message Passing Models:
Can be complex to implement.
Message ordering can be a problem.
May be less efficient for small messages
