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.

About the tutor(s)

Ondřej Meca holds a Ph.D. degree in Computer Science from VSB - Technical University of Ostrava, Czech Republic. He is currently a member of the Infrastructure Research Lab at IT4Innovations National Supercomputing Center. His research interests include verification of parallel algorithms, development of pre/post-processing algorithms for large-scale engineering problems, and development of highly-scalable linear solvers.

This event is a PRACE Training Centre (PTC) course, co-funded by the Partnership of Advanced Computing in Europe (PRACE). The main web page of the course is located on the PRACE Events Portal.

It is partially supported by The Ministry of Education, Youth and Sports from the Large Infrastructures for Research, Experimental Development and Innovations project  “e-Infrastruktura CZ – LM2018140”, partially by the PRACE-6IP project - the European Union’s Horizon 2020 research and innovation programme under grant agreement No. 823767.



This training will be an online event. Technical details about joining will be sent to the accepted registrants before the event.


Attendees should be familiar with basis concepts of MPI. For the hands-on sessions they should also know how to work on the Unix/Linux command line and be able to progam in either C/C++ or Fortran.


Obligatory registration via the PRACE Events Portal and its registration form.

Capacity and Fees

Capacity limited to 30 participants.

The training is free of charge for all participants.
