MOOC: A short introduction to MPI One-sided Communication


This online course will start on the 20th of April and it will run for two weeks, with an estimated effort of 4 hours per week. It is provided as a MOOC (Massive Open Online Course).

During this time you will be guided through the concepts of one-sided communication and learn to perform these data movements correctly and efficiently using MPI (with C and Fortran bindings). Several examples and exercises will illustrate their use and help to understand the benefits of these routines, and you also will be able to challenge your knowledge with some quizzes!

This online course has been developed by HLRS, ASTRON and SURFsara with the sponsorship of PRACE, and the registration is done for free through FutureLearn in the indicated link below.

Program and Learning outcomes

In the first week, you will get an overview and learn about the principles of one-sided communication. In the second week, we will provide more details, examples and excercises of one-sided communication.

This course will cover:

  • MPI one-sided communication
  • Window creation and allocation
  • Remote Memory Access (RMA) routines
  • Synchronization calls
  • Examples and exercises
Learning outcomes

By the end of the course, you will be able to:

  • Apply MPI one-sided communication to your communication patterns in your MPI applications
  • Explain the main advantages and disadvantages of MPI one-sided communication
  • Design your program using methods of MPI communication that prevent deadlocks and ensure the correctness of the program
  • Improve scalability of your program by substituting non-scalable solutions with scalable one-sided approaches



C or Fortran and basic knowledge of MPI.


The course language is English.
