One-Sided Communication and the MPI Shared Memory Interface

This online course will start on the 15th of November, 2021 and it will run for four 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 MPI one-sided communication and learn how to correctly and efficiently use MPI shared memory (with C and Fortran bindings). Several examples and exercises will illustrate the use of these features and help to understand their benefits. You will also be able to challenge your knowledge with some quizzes!

 

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

Program

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
  • Shared memory within MPI (programming model and usage)
  • Memory models and fast synchronization for MPI shared memory
  • Examples and exercise

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 and MPI shared memory
  • Design your program using methods of MPI communication that prevent deadlocks and ensure a correct program
  • Improve scalability of your program by substituting non-scalable solutions with scalable one-sided approaches
