The Supercomputing department provides scientific services for supercomputer users and performs research in high-performance computing and computational sciences. The department operates the HLRN-IV supercomputer system "Lise" which is part of the North-German Supercomputer Alliance HLRN.

The HPC Consulting group provides scientific and technical guidance for users to implement and perform large scientific projects on the HLRN systems. To this end, our HPC consultants bring in their research experience in various science domains like chemistry, earth sciences, physics, and life sciences to support users in the efficient use of advanced computing and storage resources to solve their scientific questions.

The HPC Systems group operates the supercomputing systems, servers, storage, networks, and gateways to data archives. The group also manages the user access, project accounting, and runs the office of the scientific board.

In close cooperation with technology providers and scientists the Algorithms for Innovative Architectures group develops new methods to make the potential of new technologies accessible for various applications, e.g., in material science and numerical mathematics. For that purpose, we design new algorithmic approaches and support the application developers with the integration into their workloads.

The Dynamics of Complex Materials group develops new methods for the simulation of complex materials. The work is focused on the development and implementation of highly parallel and scalable computational algorithms, targeting innovative HPC architectures.

In addition to the HLRN production system we operate and evaluate various innovative compute platforms configured with FPGAs and GPUs and new memory technologies like Intel Optane DCPMM (NVRAM).
