Learn how to make the most of the new shared memory interface within the MPI application. Get to grips with the new interface of MPI-3 and its practical use. Message Passing Interface (MPI) 3.0 has two new features that enable you to share memory windows. On this four-week course from Partnership for Advanced Computing in Europe (PRACE), you’ll learn how to use these new methods to maximise your use of the application.

Refresh your knowledge of MPI one-sided communication
One-sided communication, compared to two-sided communication, can help to improve performance by reducing synchronisation, having no delay in sending data, and increasing functionality and scalability.
You’ll begin by getting an introduction to MPI one-sided communication to refresh your knowledge and skills. You’ll learn how to use the new interface, examining case-use studies in the real world to further cement your learning.
Discover the principles of MPI shared memory and how to use it
You’ll explore how to split a communicator in shared memory islands and how to synchronise load and store operations. By the end of the course, you’ll understand restrictions and advanced options when using MPI-3 shared memory.
