    Big Data meets supercomputer

    At the High Performance Computing Center Stuttgart (HLRS), a project has been kicked off to combine high-performance computing (HPC) and high performance data analysis (HPDA) to tackle the subject of handling and analyzing the ever growing amount of data generated due to the continuing progress of digitization.

  • ANSYS, HLRS And Cray Set New Supercomputing Record

    ANSYS (NASDAQ: ANSS), the High Performance Computing Center (HLRS) of the University of Stuttgart and Cray Inc. have set a new supercomputing world record by scaling ANSYS Fluent to over 172,000 computer cores on the HLRS supercomputer Hazel Hen, a Cray XC40 system – enabling organizations to create innovative and groundbreaking complete virtual prototypes of their products faster and more efficiently than ever.

& Science

Research and Science are the main pillars ensuring continuous delivery of high-edge services in every area of High Performance Computing provisioning.



HLRS offers a variety of services to industry and Small and Medium Enterprises (SMEs) way beyond plain HPC resource provisioning.



Simulations transform science & development, and decision making in politics. Dealing with simulations in a rational way is therefore a scientific and societal task in itself.


The High Performance Computing Center Stuttgart (HLRS) of the University of Stuttgart is one of the three member centres of the Gauss Centre for Supercomputing (GCS). HLRS supports national and European researchers from science and industry by providing high-performance computing platforms and technologies, services and support. Services are provided in cooperation with the other two member centres of GCS and with industrial partners such as hww GmbH (T-Systems, Porsche AG) and SICOS BW GmbH.

The HLRS conducts basic and applied research in the field of high-performance computing in publicly funded national and European projects as well as industrial research activities in association with partners from research and industry. Collaborative research in the automotive field is carried out in co-operation with the Automotive Simulation Center Stuttgart (ASCS).
