What HLRS does
HLRS (Höchstleistungsrechenzentrum Stuttgart) is a German national high-performance computing center established in 1996 and affiliated with the University of Stuttgart, where it operates as a central unit of the university. It is one of three centers in the Gauss Centre for Supercomputing alongside JSC in Jülich and LRZ in Garching, and runs one of Europe's fastest supercomputers with associated AI, visualization, and quantum computing infrastructure. The center serves four primary user communities: the scientific research community (computational physics, chemistry, biology, materials science, climate, astrophysics, CFD, structural mechanics), industry and SMEs (product simulation, design optimization, manufacturing, AI/ML for product development), the public sector, and an emerging segment of AI-focused startups, SMEs, and researchers.
The technology stack centers on a multi-system supercomputing portfolio. The flagship production system is the HPE Cray EX4000 ("Hunter"), operational since February 2025 and delivering nearly twice the peak performance of its predecessor Hawk on an AMD APU architecture. The AI-optimized "HammerHAI" system (NVIDIA GB200 NVL4 by HPE, >15 Exaflops of AI inference), scheduled for Q2 2026 delivery, will integrate VAST Data DASE storage and Axelera AI inference accelerators. The next-generation "Herder" (HPE Cray GX5000) is expected in 2027. Additional systems include the NEC "Vulcan" cluster, the "Hawk AI Expansion" (HPE Apollo 6500 Gen10 Plus), the CAVE virtual reality visualization facility, and HPSS hierarchical storage.
HLRS is primarily funded by the German Federal Ministry of Research, Technology and Space (BMBF) and the Baden-Württemberg Ministry for Science, Research and Arts, with co-funding from EuroHPC JU, the Bavarian State Ministry of Science and the Arts, and the Lower Saxony Ministry of Science and Culture. Compute time is free for eligible European academic users and contract-based for industry. Ancillary revenue comes from tiered professional training (the Supercomputing Academy, with fees ranging from €55 for students to €1,370 for industry participants) and from paid industry compute contracts. The center holds ISO 27001, TISAX Level 3, and EMAS certifications, and coordinates the HammerHAI AI Factory, Germany's first AI Factory under the EuroHPC JU AI Factories initiative, with an approximately €85M project budget.
