Study Notes

What is MPI?

MPI stands for Message Passing Interface, a standardized and portable message-passing system designed for parallel computing.

Goals and Purpose

The primary goal of MPI is to enable parallel computing on a wide range of computing architectures.
MPI aims to provide a standardized interface for message passing, allowing developers to write portable parallel code.

Need for MPI

MPI is necessary because it enables parallel computing, which is crucial for solving complex problems that require large amounts of computational power.

Parallelization Methods

The most flexible parallelization method mentioned is MPI, which allows for dynamic process creation and communication.

Standardization

MPI standardizes the message-passing interface, providing a uniform way for parallel processes to communicate with each other.
