The two NHR centres, NHR@ZIB and NHR-Nord@Göttingen, share a long history of operating HPC system. This includes the successful operation of HLRN systems as well as NHR systems since 2021. The federal funding within NHR gives rise to separate some services.
Please notice that NHR@ZIB and NHR-Nord@Göttingen are two separated systems. The former HLRN does not exist any more.
