The two NHR centres, 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 services .

1. Please notice that NHR@ZIB and NHR-Nord@Göttingen are two separated systems. The former HLRN does not exist any more.
   Applications/requests submitted to one site do not affect the other site.
