Message Passing Interface (MPI) is a dominant programming model on clusters and distributed memory architectures. This course is focused on users with some experience with MPI that want to deepen their knowledge. The course briefly recapitulates basic concepts and describes them in more detail. Then, more advanced concepts will be described (e.g., one-sided communication, parallel file I/O). Attendees will be able to immediately test and understand all these constructs in hands-on sessions.
This course was originally developed by Rolf Rabenseifner (HLRS). The content level of the course is 40% for beginners, 40% for intermediate, and 20% for advanced users.

Purpose of the course (benefits for the attendees)
After the course, attendees should know the majority of MPI functions and should be aware of their appropriate use in order to write highly scalable applications.
