Leibniz Universität IT Services

Leibniz Universität IT Services (previously RRZN) provides the services of an university computing center and also functions as one of the two sites that operate the twin HPC systems of the HLRN consortium. We not only strive to provide 24 hour access to our HPC facility but also support scientists from the early stages of writing a grant application for computing time until their software applications run smoothly and efficiently on our system (HLRN ).

The Departments of Continuum Mechanics and Climatology at Leibniz University Hannover are renowned for their expertise in HPC applications in the engineering and geo sciences. Together with the HPC department at Leibniz University IT Services headed by PD Dr. Steffen Schulze-Kremer they collaborate in research and development of algorithms and applications.
