GCS combines the three largest national supercomputing centres, the High Performance Computing Center Stuttgart, Jülich Supercomputing Centre, and Leibniz Supercomputing Centre, Garching/Munich into Germany’s foremost supercomputing institution.

HLRS - High-Performance Computing Center Stuttgart

The High-Performance Computing Center Stuttgart (HLRS, Höchstleistungsrechenzentrum Stuttgart) is a research and service institution affiliated to the University of Stuttgart. It offers services to academic users and industry with a specific (but not exclusive) focus on operating leading-edge HPC systems, teaching and training for HPC programming and simulation, collaborative research with national and international partners in the realm of HPC innovation, collaboration with industry, and providing access to HPC through hww—a public-private partnership with T-Systems and Porsche. 


JSC - Jülich Supercomputing Centre

The Jülich Supercomputing Centre, located at the Forschungszentrum Jülich ("Jülich Research Centre") – one of the largest interdisciplinary research centres in Europe – provides high performance computer capacity for scientists at the Research Centre Jülich, at universities and research laboratories in Germany and in Europe, as well as for industrial partners.

The comprehensive suite of services comprises the operation and especially the development of the supercomputers and the technical infrastructure, the data storage, visualisation systems, networks and software, as well as a wealth of user support and training. The scientific peer review for projects using JCS’s HPC technologies and infrastructure is done by the John von Neumann Institute for Computing.


LRZ – Leibniz Supercomputing Centre, Garching near Munich

The LRZ (Leibniz Rechenzentrum – Leibniz Supercomputing Centre of the Bavarian Academy of Siences), is located at the Research Campus in Garching near Munich. It operates one of the three German Tier-0/Tier-1 HPC systems available for challenging research activities to national and international scientists and to industry. In addition, LRZ is the IT Service Provider for the Munich universities and colleges as well as a growing number of research organisations in Munich and throughout Bavaria.

Apart from scientific supercomputing and IT management LRZ also is a nation-wide competence center for data communication networks, collaborating with other scientific institutions and industrial partners within a number of pilot projects.
