It’s spring 2026 – what’s missing at the RWTH IT Center? The CLAIX-2025 HPC system isn’t yet in production! As part of the proven 1-cluster concept, CLAIX-2025 is intended to complement the existing CLAIX-2023 system at the Tier-2 level. We spoke with our HPC experts at the IT Center to find out why the commissioning has been delayed and what the current status is. Sascha Bücken, Group Leader “Server, Storage, HPC,” Tim Cramer, Group Leader “HPC CORE,” and Christian Terboven, Chief HPC Officer, answer the question on the minds of researchers at RWTH Aachen and across Germany:
HPC Events 2026: From Basics to Simulation

High Performance Computing (HPC) plays a central role in many fields of research—from engineering and data analysis to the simulation of complex physical processes. The IT Center therefore regularly organizes workshops, training sessions, and community events focused on HPC to support researchers and students as they get started and further develop their skills.
In 2026, the event program once again offers numerous opportunities to explore topics related to high-performance computing, scientific programming, and numerical methods. Some events have already taken place, and many more are scheduled throughout the year.
HPC Review 2025 – Developments, Collaborations and Highlights

For the High-Performance Computing (HPC) division at the IT Center of RWTH Aachen University, 2025 was marked by international exchange, practice-oriented workshops, sustainability initiatives, technological developments, and numerous activities related to HPC use and competence building. In this review, we summarize key events, projects, and successes.
Green HPC: Sustainability in the Data Centers of Tomorrow

Digital technologies have become an integral part of science and industry – but data centers are among the biggest energy consumers in the IT sector. High-performance computers in particular are essential for complex calculations in research, but at the same time cause high electricity costs and CO2 emissions. To meet these challenges, RWTH Aachen University is focusing on innovative solutions for energy efficiency and sustainable resource utilisation.
HPC Landing Page: High Performance Computing
High Performance Computing (HPC) at RWTH Aachen University acts as a central building block to support the simulation sciences by enabling the development of scalable algorithms and software. Of central importance for innovation in business and society, RWTH High Performance Computing offers various services and research opportunities based on a first-class infrastructure. This means that HPC applications can be executed efficiently and in a scalable manner and large amounts of data can be processed securely and quickly.
Implementation is supported by projects such as JARA, HPC.NRW and, in particular, the National High Performance Computing Center for Computational Engineering Science (NHR4CES). You can read more under the category HPCnews on our blog.
CodeClubMG Visit to the Chair of HPC

Christian Terboven during the cluster tour
On April 23, 2024, we had the pleasure of welcoming a group of dedicated CodeClubMG students to the Chair of High Performance Computing (Computer Science 12). The visit was organized by Tom Hilgers, Master student of Computer Science and part of the operational management of CodeClubMG. “With the excursion, we bring the students closer to the world of computer science. We were able to show them that computer science is not just about programming, but a very diverse subject area,” Tom tells us.
Review: VI-HPS Porting & Tuning Workshop 2024

What happened to the well-known aiXcelerate event this year? Well, who noticed?
The VI-HPS Porting & Tuning Workshop 2024 took place at the end of February! This workshop compensated for the aiXcelerate 2023, which did not take place.
That’s why we’re reporting on this year’s VI-HPS Porting & Tuning Workshop in the following blog post.
CLAIX-2023: New Supercomputer at the RWTH

Alongside theory and experiment, computer-aided simulations are described as the third pillar of science. It is therefore of great importance for technical universities such as RWTH Aachen University to continuously expand their capacities in the field of high-performance computing and to further develop their capabilities. We are therefore delighted that the full installation of the new Aix-la-Chapelle cluster (CLAIX) has been completed! Under the label CLAIX-2023, the new high-performance computer not only offers powerful Intel Xeon 8468 Sapphire Rapids CPUs with a total of 96 cores per computing node for a significant increase in performance. In addition, it has 52 special servers for artificial intelligence and machine learning applications, each with four NVIDIA H100 GPUs, which enables an impressive total performance of over 14 PFLOPS in the ML segment alone.
