Supercomputing at LRZ
The LRZ makes pioneering simulations and Big Data analyses possible in fields such as astrophysics, climatology, medicine and engineering using powerful high-performance computers such as the SuperMUC-NG. This is why the LRZ is one of the leading supercomputing centres in Europe.
First in high-performance computing, then supercomputing: The LRZ has been developing and managing state-of-the-art supercomputing infrastructures for more than 60 years, supporting researchers with innovative technologies and bespoke solutions for complex calculations. This expertise has allowed us to establish ourselves as a reliable partner for research and, in collaboration with scientists, produce outstanding results which are also making a name for themselves on the international stage.
As an integral part of the national and European supercomputing community, the LRZ works closely with its partners at the Gauss Centre for Supercomputing (GCS), the Gauß-Allianz, the National High Performance Computing (NHR) Alliance and the EuroHPC Joint Undertaking Initiative as well as many other renowned research institutes around the world, to continuously improve and expand the technologies and methods for computer-aided scientific computing.
Accelerating world-class science
Analysing measured valued, developing models, calculating simulations: If research can process knowledge more rapidly and efficiently, we will be able to increase our knowledge more quickly and better solve the challenges of the present. That is why we do more than just provide scientists and researchers with high-performance technology and innovative tools so that they can reduce the time it takes to acquire knowledge from research.
SuperMUC-NG
More than 311,000 computing cores and a main memory of around 720 terabytes: SuperMUC-NG was launched in 2019 and is our leadership class high-performance computer at LRZ. It processes an incredible 26.9 petaflops per second or 26.9 hundred trillion (a number with 14 zeros) floating-point operations. The SuperMUC-NG is also the first system at LRZ to use graphics processors (GPU) and CPUs to enable AI processes.
CoolMUC
Our CoolMUC series has been a reliable resource for scientists in Bavaria for over 20 years. The fourth generation of CoolMUC was launched in December 2024: The cluster has 119 computing nodes and a total of 12,448 cores, and will soon undergo expansion using AI-capable processors. This allows researchers to include statistical analyses in their simulation calculations and produce more scenarios much more quickly.
The Compute Cloud
The LRZ Compute Cloud is made up of 82 compute nodes, 32 GPU nodes and one huge node. It is used by scientists who need rapid computer resources for their own services or for testing software and code. Research groups can also create their own virtual machines (VMs) in the cloud and configure them according to their specific needs.
At LRZ, you can learn programming languages as well as how to work with high-performance systems. Above all, we focus on personal support and a comprehensive, up-to-date training programme. And it goes without saying that LRZ specialists are continuously optimising the computing power available, the infrastructure for data management and the user-friendliness of technology and tools.
Workshops & Training
We won’t leave you to fend for yourselves when it comes to our supercomputers: At LRZ, our experts will provide you with rapid, personal support and help you find the right course for learning how to use and programme supercomputers. And if you have any questions that need to be answered quickly or are looking to share experiences, we recommend attending the HPC Lounge on Thursdays at the LRZ: Meet our experts.
The experts in our LRZ application labs support researchers across various disciplines. We are available as mentors, provide support with code optimization and bring the necessary expertise in the respective domain sciences. Of course we are also active in scientific projects such as CompBioMed, ClimEx or dealii-X.

The foundations of disaster control
SeisSolSeisSol is impressive in that it showcases the advantages of supercomputing: For this project, researchers developed the formulae and simulation programmes with which measurement data from recent earthquakes and tsunamis can be calculated – and risks can be predicted. Research lays the foundations for disaster control thanks to supercomputing.

Peering into the black hole
Event Horizon TelescopeProf Luciano Rezzolla’s team at the Goethe University Frankfurt researches black holes and matter. Bringing this knowledge to bear, they managed to produce the theoretical calculations and explanations for the first realistic image of a black hole in the Milky Way using the Event Horizon Telescope (EHT) in 2022. This work earned Professor Rezzolla the HPC Excellence Award from the Partnership for Advanced Computing in Europe (PRACE) in 2024.

A better explanation of the lung
Thermodynamics are in play when you breathe: With this knowledge, the professorial chair of numerical mechanics at the Technical University of Munich developed a digital, spatial model of the human lung. Not only did it change how we see the largest organ in the human body, but the digital twin of the lung also served as the basis for a piece of software for ventilating premature babies with underdeveloped lungs, and the programme also helped to make ventilation safer for adults during the COVID-19 pandemic.
HPC Results Books
It’s worth taking a closer look: Every two years, the LRZ collects successful, exciting or fascinating projects and research results that have been developed using its supercomputers and publishes them in a book. The “High Performance Computing in Science and Engineering” series presents climate models, breakthroughs in materials science, simulations of the universe and its phenomena as well as research results from engineering and earth sciences, but most importantly: successful researchers and scientists. Discover the power of supercomputing – and learn about what added value LRZ-supported projects create for all of us.
The fascination with supercomputing
Can we inspire you? You will, of course, find many more reports and news items about fascinating research results that have been created with the help of LRZ’s supercomputers and its partners. The media of the German and international HPC community will keep you in the loop, and we recommend taking more than just a cursory glance.
