Revolutionizing Science: 25 Years of HPC at LRZ
The Leibniz Supercomputing Centre (LRZ) has been a powerhouse of scientific discovery, pushing the boundaries of high-performance computing (HPC) in Germany and Europe.
Since the year 2000, LRZ has been a key player in the HPC arena, with a rich history that began with the HLRB 1, a supercomputer ranked fifth globally, boasting an impressive 1.6 billion floating-point operations per second. But here's where it gets interesting: this was just the beginning of LRZ's journey into the world of HPC.
A Journey of Innovation
By 2007, LRZ's collaboration with the Gauss Center for Supercomputing (GCS) had expanded its influence internationally. This partnership has set the stage for numerous scientific breakthroughs and technological advancements.
Unlocking Scientific 'Aha' Moments
The LRZ supercomputers' processing power has grown exponentially, with storage capacity doubling every year. But the real magic lies in the scientific revelations these machines have facilitated:
- A Paradigm Shift in Lung Anatomy: LRZ's supercomputer, guided by TUM scientists, challenged conventional wisdom by revealing the human lung's sponge-like structure, larger than the skin when unfolded.
- Earth's Continental Evolution: LMU researchers used LRZ's HPC to simulate the formation of continents over millions of years, resulting in captivating visuals displayed at the American Museum of Natural History.
- Insect and Bird Evolution: The 1Kite project reconstructed the evolutionary history of insects and birds, solidifying LRZ's impact on fundamental biological research.
- Astrophysics and Neutrino Discovery: The Millennium TNG project leveraged LRZ's HPC to simulate dark matter, leading to the detection and measurement of neutrinos.
Pushing the Limits of Computing
The demand for HPC resources is insatiable, as evidenced by the 2021 and 2025 interstellar turbulence simulations. The latter required a staggering 30 terabytes of storage and 138,240 computing cores, showcasing the ever-growing need for computational power.
HPC's Reach Extends Beyond Astrophysics
LRZ's usage data reveals a diverse user base, including biologists, medical researchers, and climate scientists, all leveraging HPC for simulations and modeling alongside experiments. This expansion is facilitated by the Competence Network for Scientific High-Performance Computing (KONWIHR), which actively promotes HPC integration across various disciplines in Bavaria.
AI and HPC: A Powerful Alliance
The future of HPC at LRZ is intertwined with artificial intelligence (AI). With the expansion of SuperMUC-NG, featuring 27,000 CPUs and 1,000 GPUs, AI methods are enhancing traditional simulations. Additionally, LRZ's connection to quantum computers and the introduction of photonic processors in 2025 open up new frontiers in computing.
Celebrating a Quarter-Century of HPC Excellence
On October 13, 2025, LRZ commemorated 25 years of national HPC in Bavaria with a ceremony and scientific symposium. Prof. Dieter KranzlmÞller, Chairman of LRZ, emphasized the center's commitment to serving a broad user community and advancing global problem-solving. Prof. Dr. Arndt Bode, former Chairman, highlighted LRZ's unique infrastructure and its impact on energy efficiency and user experience.
Looking Ahead: HPC's Ever-Expanding Horizons
As LRZ continues to evolve, the integration of AI and quantum computing promises to revolutionize scientific research. The center's journey from HLRB to SuperMUC-NG exemplifies the relentless pursuit of technological excellence. And this is the part most people miss: the potential for HPC to transform not just science but also our understanding of the world.
