Parallel Programming Workshop (Train the Trainer)

The Train the Trainer Program is provided in conjunction with the regular course Parallel Programming Workshop (MPI, OpenMP and Advanced Topics). Whereas the regular course teaches parallel programming, this program is an education for future trainers in parallel programming.

Too few people can provide parallel programming courses on the level that is needed if scientists and PhD students want to learn how to parallelize a sequential application or to enhance parallel applications. Within Europe, currently only six PATC centres and several other national centres provide such courses on a European or national level. We would like to assist further trainers and centres to also provide such courses in the whole Europe or at least within their countries.

Prerequisites and content levels


You are familiar with parallel programming with MPI and OpenMP on an advanced level and skilled in both programming languages C and Fortran (or Python for the MPI part).

Your goal: You want to provide MPI and OpenMP courses for other scientists and PhD students in your country, i.e., you would like to provide at least the first three days of the regular course as a training block-course to PhD students.

Background: (a) Your centre supports you to provide such PhD courses in a course room at your centre. The course room is equipped at least with one computer/laptop per two (or three) students and has access to an HPC resource that allows MPI and OpenMP programming in C and Fortran. To this purpose, a center may send two or three TtT participants together to this course. Additionally, you may have already participated as a regular participant in one of our other courses, so that you are already familiar with all the exercises.
Or (b), you as a future trainer would like to co-operate with a centre with the necessary course infrastructure in your country.

What does this Train the Trainer Program provide?

  • We provide you with all necessary teaching material on a personal basis, i.e., with the copyright to use it and to provide pdf or paper copies to the students in your PhD courses.
  • We provide all exercise material.
  • You will listen the lectures, so that you can get familiar with the training material.
  • During the exercises, you will help the regular students to correct their errors. The regular students are advised to request help if they are stuck for more than a minute. You will be trained to detect their problems as fast as possible (typically in less than a minute) and to provide the students with the needed help.
  • For this, and if possible, we will pair you with other TtT participants, so that you can help at a maximum of problems.
  • When the participants start with the exercise, all TtT participants will receive a short (5 minutes) briefing on important aspects and usual problems with this exercise.
  • Optionally, we can also meet during the few lectures that are not part of the TtT program (e.g., those by external lecturers), or in the morning 8:15-8:30 every day.

The Train the Trainer Program includes the curriculum from Monday until Friday according the course agenda. The Train the Trainer Program starts on Monday with a short introductory meeting at 8:15 am. On Tuesday, Wednesday, and Friday we will have a short review/discussion meeting after the course. On Thursday evening we will have an additional meeting and dinner for all participants of this TtT program. On Friday, we will wrap up with a short review at the end (17:00-17:30).

Additional prerequisites:

  • You should be present the whole time during the course week.
  • During the course week, you should be prepared to be totally offline from your regular business during the course hours because during the lectures you should learn details about the slide content and how to teach it, and during the exercises you support the participants. 
  • Please expect the TtT course to finish 30-60 minutes later than the official schedule of the regular course.
  • If you are accepted to the TtT course, you will receive four weeks before the course an updated pdf of the MPI and OpenMP course slides. The exercises are available here. It is required that you prepare the MPI and OpenMP exercises before the course starts, so that you can assist the participants during the exercises.

Learning outcomes

This course provides scientific training in Computational Science for the future trainers.

On-site course & COVID rules

Besides the content of the training itself, another important aspect of this event is the scientific exchange among the participants. We try to facilitate such communication by

  • offering common coffee and lunch breaks and
  • working together in groups of two during the exercises (if desired by the individual participants and permitted by the COVID-19 rules).

For your safety, we will only allow fully vaccinated or fully recovered or COVID-19 negative tested participants on all days. You must wear a medical face mask or FFP2 mask everywhere on site. If a distance of 1.5 m cannot be guaranteed inside, e.g., if you are working in pairs in exercises, it must be an FFP2 mask. Details can be found on the registration page.

We strongly recommend to choose travel options and hotels with the possibility to cancel (even close to the event) because we might be forced to deliver the course as an online course.

Registration information

Register via the button at the top of this page and complete the "required application letter" as explained below.

After registration:

  • You will receive an automated response with your registration data.
  • You forward this data to rabenseifner(at) together with an required application letter (about one page) that gives us information about your background (e.g., your expertise in using MPI and OpenMP), why you apply for this training and your future plans how to use our material (or your material) in your own future courses.
  • Without this required application letter, your registration will be canceled.
  • You will receive a personal answer whether your application to this Train the Trainer Program has been accepted.
  • If your application has been accepted, you will receive an invoice for the course fee.
  • If your major goal is to learn about MPI and OpenMP, then please register for the regular course.


Monday-Tuesday: This is an HLRS course with the following fees:

  • Students without master’s degree or equivalent at a German university: 30 EUR.
  • Students without master’s degree or equivalent at a university in an EU, EU-associated or PRACE country: 30 EUR.
  • PhD student or employee at a German university or public research institute: 60 EUR.
  • PhD student or employee at a university or public research institute in an EU, EU-associated or PRACE country other than Germany: 120 EUR.

Wednesday-Friday: For participants of the above categories, this course is sponsored by the PRACE PATC program, i.e., there are no course fees if you register only for Wednesday-Friday.

For all other participants (Mo-Fri), this course is an HLRS course with the following fees:

  • Students without master’s degree or equivalent at a university outside of EU, EU-associated or PRACE countries: 40 EUR.
  • PhD students or employees at a university or public research institute outside of EU, EU-associated or PRACE countries: 360 EUR.
  • Other participants, e.g., from industry, other public service providers, or government: 960 EUR.

Link to the EU and EU-associated (Horizon Europe), and PRACE countries.

Our course fees include coffee breaks (in classroom courses only).
