The Leibniz Supercomputing Centre of the Bavarian Academy of Sciences and Humanities (Leibniz-Rechenzentrum, LRZ) provides comprehensive services to scientific and academic communities by:

  • Giving general IT services to more than 100,000 university customers in Munich and for the Bavarian Academy of Sciences
  • Running and managing the powerful communication infrastructure of the Munich Scientific Network (MWN)
  • Acting as a competence centre for data communication networks
  • Being a centre for large-scale archiving and backup, and by
  • Providing High Performance Computing resources, training and support on the local, regional, national and international level.

Research in HPC is carried out in collaboration with the distributed, statewide Competence Network for Technical and Scientific High Performance Computing in Bavaria (KONWIHR).

First German National Center

Based on a long tradition in supercomputing at University of Stuttgart, HLRS (Höchstleistungsrechenzentrum Stuttgart) was founded in 1995 as the first German federal Centre for High Performance Computing. HLRS serves researchers at universities and research laboratories in Europe and Germany and their external and industrial partners with high-end computing power for engineering and scientific applications.

Service for Industry

Service provisioning for industry is done to gether with T-Systems, T-Systems sfr, and Porsche in the public-private joint venture hww (Höchstleistungsrechner für Wissenschaft und Wirtschaft). Through this co-operation industry always has access to the most recent HPC technology.

Bundling Competencies

In order to bundle service resources in the state of Baden-Württemberg HLRS has teamed up with the Steinbuch Center for Computing of the Karlsruhe Institute of Technology. This collab oration has been implemented in the non-profit organization SICOS BW GmbH.

World Class Research

As one of the largest research centers for HPC HLRS takes a leading role in research. Participation in the German national initiative of excellence makes HLRS an outstanding place in the field.

The Jülich Supercomputing Centre (JSC) at Forschungszentrum Jülich is committed to enabling scientists and engineers explore some of the most complex grand challenges facing science and society. Our research is performed through collaborative infrastructures exploiting extreme-scale supercomputing and federated data services.

Provision of supercomputer resources of the highest performance class for projects in science, research and industry in the fields of modeling and computer simulation including their methods. The selection of the projects is performed by international peer-review procedures implemented by the John von Neumann Institute for Computing (NIC), GCS, and PRACE.

Supercomputer-oriented research and development in selected fields of physics and other natural sciences by research groups and in technology, e.g. by doing co-design together with leading HPC companies.

Higher education for master and doctoral students in close cooperation with neighbouring universities.

Implementation of strategic support infrastructures including community-oriented simulation laboratories and cross-sectional teams, e.g. on mathematical methods and algorithms and parallel performance tools, enabling the effective usage of the supercomputer resources.
