This practical course comprises two parts: firstly, a crash course on the basics of High-Performance Computing is delivered during a one-week block tutorial. Including hands-on exercises, it will cover theoretical knowledge regarding parallel computing, high-performance computing, supercomputers, and the development and performance analysis of parallel applications. Practical demonstrations will encourage you to utilize the GWDG cluster system to execute existing parallel applications, start developing your own parallel application using MPI and OpenMP, and to analyze the performance of these applications to ensure they run efficiently.
On the first day of the tutorial, we will help you form groups of three four people to work on the exercises. We will form a learning community that will blend into the second part of the course.
For students, we will present on the last day of the tutorial a group assignment that you will have to solve in pairs.
If you are just interested to learn about parallel programming and don't need credits, you can join only the first part of the course and gain a certificate.
This course is suitable for Bachelor and Master students and the block course is suitable for GWDG academy participants. We aim to form suitable learning groups for all attendees.

Please note that we plan to record sessions (lectures and seminar talks) with the intent of providing the recordings via BBB to other students but also to publish and link the recordings on YouTube for future terms. If you appear in any of the recordings via voice, camera or screen share, we need your consent to publish the recordings. See also this Slide.
The students will be able to
The block seminar contains sessions that contain short lectures followed by hands-on exercises that teach the most relevant aspects of the concepts and tools. The hands-on typically starts with a short tutorial as a walk-through followed by guided learning based on a provided worksheet with exercises and descriptions. Participants can take breaks as necessary during guided learning.
Computer science students, please attend still your lectures, this year the easter vacations are unfortunately located such that scheduling is difficult.
This part is attended by BSc/MSc students and GWDG academy participants
Everyone, please prepare via the information given in this sheet Prep exercise
Introductory day – optional for computer students Slides
Students, please register using StudIP. GWDG Academy participants, please register there.
This remaining part is mandatory for BSc and MSc students to obtain the credits but can be skipped if you just want to join the block course.
In order to obtain the credits, you will parallelize a non-trivial problem of your choice using the concepts and tools learned during the block course. As an alternative option, you could choose from an administrative topic that we derive from a practical problem at the GWDG.
Firstly, you will decide upon a problem you like to solve, then you will create a sequential solution to this problem, and lastly, you apply the experience of the block course to parallelize your application and analyze its scalability. You need to prepare a presentation for your fellow students as well as document your solution in a report. Both the presentation and the report are due at the end of the term and will be assessed and marked.
To obtain the credits, students must develop their (own) group project. A presentation of 20 min and report (max 15 pages per group member) must be created. The mark consists of 30% presentation and 70% report.
The report must be submitted as a PDF file. The source code must be handed in as well. Optimally as a Gitlab or Github repository.
This attendance of the virtual project meetings is mandatory for BSc and MSc students to obtain the credits.
There will be three project meetings in which the groups introduce their results. These meetings are not marked but provide valuable feedback toward your project. In the first seminar, the project idea and rough implementation plan are shared. The second seminar will introduce a report and gives you the opportunity to ask questions regarding the preparation of the report. In the final meeting, the project results are shared.
Projects should cover either the creation and parallelization of an interesting problem such as:
Most important is the correct parallelization (possibly with alternatives) and evaluation. Detailed knowledge of numerics or a precise representation of the model is not required.
Alternatively, we provide a list of specific topics that are motivated by our needs in the data center, these may cover administrative aspects as well. We are open to further suggestions.
Examples can be found in the course from last year or here. Have a look at the results and videos generated.
For a generic parallelization project, some contents should be worked on and accordingly included in the presentation and elaboration, the aspects are:
This is a list of topics for the individual projects that are motivated by our needs in the data center. We welcome it if you propose your own simulation, parallelization, or administrative topic. Even for our suggested topics, you will have some room for developing the topic in the direction of your choice.
