HLRS is a leading European high-performance computing centre based in Stuttgart, Germany, providing supercomputing resources, research, and services for computational science and engineering. It supports scientists, engineers, and industry partners across domains including climate science, fluid dynamics, materials science, and bioinformatics. HLRS operates large-scale computing systems, fosters collaborations with universities, research institutes, and companies, and engages in education and outreach to train users in parallel computing, data analytics, and visualization.

History

HLRS traces its institutional development to computing initiatives in Baden-Württemberg and national German research planning, evolving alongside centres such as Deutsches Elektronen-Synchrotron, Max Planck Society, Fraunhofer Society, Helmholtz Association, and Leibniz Association. Early milestones paralleled procurement decisions influenced by trends set by Cray Research, IBM, Intel, AMD, and Fujitsu. Its programmatic growth aligned with projects funded under frameworks involving European Commission, Horizon 2020, Framework Programme 7, and collaborations with German Research Foundation and Baden-Württemberg Stiftung. Over time HLRS integrated technologies from vendors like NVIDIA, ARM Holdings, IBM Research, Siemens, and Hewlett Packard Enterprise while participating in initiatives with organizations such as PRACE, Gauss Centre for Supercomputing, European Grid Infrastructure, and Open Science Grid.

Organization and Governance

HLRS governance reflects structures found in institutions like University of Stuttgart, State of Baden-Württemberg, Federal Ministry of Education and Research (Germany), Baden-Württemberg Ministry of Science, Research and the Arts, and boards resembling those at MAX IV Laboratory, European Southern Observatory, and CERN. Leadership roles interact with academic units comparable to Technical University of Munich, RWTH Aachen University, Karlsruhe Institute of Technology, and administrative frameworks used by German Aerospace Center. Decision-making on procurement, user allocation, and strategic directions involves stakeholders from SAP SE, Bosch, Daimler AG, Porsche AG, and regional universities including University of Tübingen and University of Hohenheim. HLRS staff include research scientists, system administrators, visualization experts, and project managers with ties to programs at Alexander von Humboldt Foundation and fellowships such as Marie Skłodowska-Curie Actions.

Supercomputing Facilities and Systems

HLRS houses successive generations of supercomputers similar in scale and architecture to systems deployed at Oak Ridge National Laboratory, Lawrence Livermore National Laboratory, Argonne National Laboratory, and Sandia National Laboratories. System architectures have incorporated processors and accelerators from Intel Xeon, AMD EPYC, NVIDIA Tesla, Fujitsu A64FX, and interconnects akin to InfiniBand, Omni-Path, and Slingshot. Storage and data management approaches resemble large deployments at European Centre for Medium-Range Weather Forecasts, National Center for Atmospheric Research, and Los Alamos National Laboratory using parallel file systems like Lustre and BeeGFS. HLRS supports software ecosystems including MPI implementations from Open MPI and MPICH, programming models promoted by OpenACC, OpenMP, CUDA, and tools provided by GitHub, Eclipse Foundation, GNU Project, and Intel Parallel Studio. System procurement, benchmarking, and ranking have featured participation in lists and comparisons used by TOP500, Green500, HPCG, and performance centers such as Mont-Blanc Project.

Research and Applications

Research at HLRS spans computational fluid dynamics similar to studies at Imperial College London and TU Delft; climate and earth system modeling in line with efforts at Met Office and Max Planck Institute for Meteorology; and materials modeling comparable to projects at MIT and ETH Zurich. Application domains include aerodynamics for aerospace firms like Airbus and Rolls-Royce, combustion research akin to work at NASA Glenn Research Center, cardiovascular flow simulations related to studies at Johns Hopkins University, and bioinformatics workflows reminiscent of projects at European Bioinformatics Institute and Wellcome Sanger Institute. HLRS researchers publish with collaborators at Stanford University, Harvard University, University of Cambridge, Princeton University, California Institute of Technology, and engage in reproducibility practices promoted by arXiv, Zenodo, and ResearchGate.

Collaborations and Partnerships

HLRS maintains collaborations with pan-European infrastructures such as PRACE and the Gauss Centre for Supercomputing, and partnerships with industrial and academic entities like Siemens AG, BASF, Thyssenkrupp, Volkswagen, Robert Bosch GmbH, E.ON, EnBW, Fraunhofer Institute for Industrial Engineering, Max Planck Institutes, Technical University of Berlin, Karlsruhe Institute of Technology, and University of Stuttgart. International ties connect HLRS to consortia including EuroHPC, US Department of Energy National Laboratories, Japanese RIKEN, National Supercomputing Center in China, and initiatives with Google, Microsoft Research, Amazon Web Services, NVIDIA Research, and ARM Research. Collaborative projects often operate under funding frameworks such as Horizon Europe, European Structural and Investment Funds, and bilateral agreements with ministries like Federal Ministry for Economic Affairs and Climate Action.

Education and Outreach

HLRS offers user training, workshops, and summer schools comparable to programs at International Centre for Theoretical Physics, Zuse Institute Berlin, NERSC Training, and XSEDE. Teaching and capacity building include courses on parallel programming, performance engineering, and data visualization running with partners such as Coursera, edX, EuroHPC training, and university curricula at University of Stuttgart and Technical University of Munich. Outreach engages the public through events modeled on HPC User Forum, Supercomputing Conference (SC), and cooperative exhibits with museums like Deutsches Museum and science festivals including Stuttgart Science Festival. HLRS supports doctoral research and joint supervision with institutions participating in networks like European University Association and awards linked to prizes such as ACM Gordon Bell Prize and IEEE Seymour Cray Award.
