NHR@ZIB and NHR-Nord@Göttingen share a long history of operating HPC systemsystems. This includes the successful operation of HLRN systems time during the HLRN era as well as within the NHR systems alliance since 2021. The federal funding within of the NHR gives rise to separate some of our services.
