Announcements
This webpage contains the training hosted by SuperComputing Luxembourg, the National Competence Centre in High-Performance Computing. Trainings are developed by the partner organizations of SuperComputing Luxembourg, the University of Luxembourg and LuxProvide.
Our upcoming events are listed below. For more information about our schedule and upcoming trainings, please follow our even calendar.
Gray Scott summer school 2026¶
The Gray Scott School is an advanced training program dedicated to High-Performance Computing (HPC), led by experts from IJCLab, CNRS, Inria, LUPM, LPNHE & LISN. The training focusses on programming and optimization on Heterogeneous Architectures.
This summer school, is organized yearly by Laboratoire d’Annecy de Physique des Particules (LAPP, CNRS – CNRS Nuclei & Particles), in collaboration with the CC-FR Competence Centre, and is entirely free of charge. Participants can attend the event on site in Annecy, France, on one of the satellite sites around the world, or online. The University of Luxembourg HPC facility is hosting a satellite site for the event every year.
Gray Scott satellite sites
Satellite sites allow for remote attendance of the Gray Scott school. Satellite sites provide
- an HPC platform where participants can run the practical examples, and
- a seminar room with bidirectional audiovisual link to the man site in Annecy,
to allow seamless participation to the school activities.
It is also possible to follow the school online, but most practical examples require access to an HPC system.
The programme of the 2026 iteration¶
The Gray Scott school 2026 covers the optimisation of computations on different types of hardware (CPU, GPU), presenting their respective characteristics, architectures and bottlenecks. It covers generic optimisation methods applicable to all types of hardware, as well as the various libraries, technologies and languages available to achieve the best possible performance. Ideally, the peak performance of the machine.
Through hands-on sessions, lectures, and regular technical webinars, the school equips participants with the skills needed to design, optimize, and scale high-performance applications.
The summer school is the in person component of the Gray Scott School 2026 that runs throughout the year. You can follow the weekly online seminars, Gray Scott Thursdays, throughout the year.
Satellite site in Luxembourg¶
The University of Luxembourg HPC facility is hosting a satellite site for the 2026 iteration of the school.
- Participants in the site will be given access to the HPC facility of the University of Luxembourg for the practical work.
- There are 30 places available.
- Participants can follow any number of training sessions.
- CCFR will provide certificates of attendance for the session that a participant follows.

Introduction to OpenACC for Heterogeneous Computing¶
Participants from this course will learn GPU programming using the OpenACC programming model, such as compute constructs, loop constructs and data clauses. Furthermore, understanding the GPU architecture and how parallel threads blocks are created and used to parallelise the computational task. Moreover, GPU is an accelerator; hence, there must be a good understanding of memory management between the GPU and CPU, which will also be discussed in detail. Finally, participants will also learn to use the OpenACC programming model to accelerate linear algebra (routines) and iterative solvers on the GPU. Participants will learn theories first and implement the OpenACC programming model with mentors' guidance later in the hands-on tutorial part.
Learning outcomes¶
After this course, participants will be able to:
- Understanding the GPU architecture (and also the difference between GPU and CPU)
- Streaming architecture
- Threads blocks
- Implement the OpenACC programming model
- Compute constructs
- Loop constructs
- Data clauses
- Efficient handling of memory management
- Host to Device
- Unified memory
- Apply the OpenACC programming knowledge to accelerate examples from science and engineering:
- Iterative solvers from science and engineering
- Vector multiplication, vector addition, etc.
Prerequisites¶
Priority will be given to users with good experience with C/C++ and/or FORTRAN. No GPU programming knowledge is required; however, knowing the OpenMP programming model is advantageous.
GPU Compute Resource¶
Participants attending the event will be given access to the MeluXina supercomputer during the session. To learn more about MeluXina, please consult the Meluxina overview and the MeluXina - Getting Started Guide.

SCynergy 2026¶
SCynergy is the premier supercomputing event of Luxembourg, where you can meet users and providers of HPC services, and other members of the HPC ecosystem of Luxembourg. The event is organized annually.
The following sessions were presented in 2026 by the University of Luxembourg and the National Competence Center.
An introduction to HPC: Basic concepts and techniques¶
This talk presents an overview of the available technologies in HPC systems. The aim is to provide a roadmap that experienced HPC users can use to gain a better understanding of the HPC system they are using, improve their skills, and ultimately use the available resources more efficiently.
