This topic provides an overview of the features of the Message Passing Interface (MPI), a specification that is the de facto standard for distributed memory computing. It describes the differences among various MPI versions and implementations and presents a brief sketch of how to incorporate MPI into your development.


After you complete this topic, you should be able to:

  • Describe why people use MPI and identify appropriate use cases.
  • Name four characteristics of high-quality MPI implementations
  • Choose among available MPI implementations
  • Plan how to incorporate MPI into your workflow
