NHR@ZIB and NHR-Nord@Göttingen share a long history of operating HPC systems. This includes the successful time during the HLRN era as well as within the NHR alliance since 2021. The federal funding within of the NHR gives rise to separate some of our servicesservices of the Berlin and Göttingen sites. We are looking forward to see you on our present and our new future NHR systems.

Please notice that NHR@ZIB and NHR-Nord@Göttingen are two separated systems. The former HLRN does not exist any more.
