21 Racks The nodes of phase 1 are placed in 10 racks in an air-cooled area and the 11 racks of phase 2 are operated with direct hot water cooling.
1 423 Compute Nodes 449 compute nodes belong to phase 1 and are equipped with Intel Xeon Gold 6148 SKL-SP CPUs. The other 974 compute nodes of phase 2 are equipped with Xeon Platinum 9242 CLX-AP CPUs.
111 464 CPU Cores These are distributed over phase 1 and phase 2 with 17 960 and 93 504 cores respectively.
100 Gbit/s Interconnect A 100 Gbps Intel Omni-Path network offers low latency and high bandwidth with a fat-tree topology and combines the two phases of Emmy with two 896 port director switches in a single fab
5.95 PetaFlop/s This result was achieved during the LINPACK benchmark, putting Emmy in 47th place on the November 2020 Top 500 list.
478 TB RAM Across all 1 423 nodes are 478 TB of memory available.
8.4 PiB Storage A total of 8.4 PiB of storage capacity is available on global parallel file systems, divided into 340TiB for the GPFS-based Home and 8.1 PiB for the Lustre-based Work file system.
6,4 PiB Tape Storage To archive their results, users have a total of 6.4 PiB of tape storage with a 120 TiB hard disk cache at their disposal.

HPC on Campus

HPC-Systems hosted by GWDG on the Göttingen campus.

The GWDG, as the joint data center of the University of Göttingen and the Max Planck Society, hosts the Scientific Compute Cluster (SCC) to ensure access to a local HPC-system for all scientists. In this role, the GWGD also hosts intitute-owned systems in the scope of the GöHPC cooperation in an integrated hosting concept. In addition, the GWDG will be hosting two external systems: already now the Göttingen HLRN-IV system and from the end of 2020 on the Göttingen site of the HPC initiative of the German Aerospace Center (DLR).

Research and Science

Research, teaching and consultation on HPC on the Göttingen campus.

In addition to IT operations, one of the GWDG's main areas of activity is research and  science. This is underlined by the various projects and the chairs of Prof. Dr. Ramin Yahyapour and Prof. Dr. Philipp Wieder. The HPC team is also commited to the promotion of young scientists by supporting teaching and supervising master and doctoral theses.

The GWDG and in particular the HPC team are in close contact with the researchers who work on the HPC systems of the GWDG. This results in various methodological and application science synergies and projects, which are consolidated under the label GöHPC.
