Background The ZIB has more than 40 years of experience as an HPC center and, since January 2021, has been one of the nine centers of the nationwide HPC alliance "NHR" (National High-Performance Computing, ), which is funded by the federal and state governments.

We operate computing and storage resources at the highest performance level and support scientists in their computationally intensive projects. Currently, our HPC system "Lise," with a peak performance of 8 PFlop/s, provides a platform for carrying out demanding computational tasks and data analysis workflows to solve complex scientific problems. The "Lise" system comprises 130,000 processing cores, 20 PB of persistent online storage, and 256 GPUs.

The NHR Center at ZIB brings together the technical expertise needed for the efficient operation of HPC resources and provides users with system-specific consulting. The diverse and demanding tasks ahead for the reliable operation of HPC systems require conceptual work in the areas of energy efficiency, heterogeneous computer architectures with GPUs and storage systems, as well as their implementation in production operations in collaboration with the staff of the Supercomputing Systems group.

The focus is particularly on innovative IT technologies and their application in scientific environments, as well as the administration of complex HPC computing architectures featuring accelerators (GPUs, FPGAs), high-speed networks, and modern storage systems.
