DLR
In the scope of a cooperation between the GWDG, the University of Göttingen and the German Aerospace Center (“Deutsches Zentrum für Luft- und Raumfahrt” - DLR), the GWDG hosts one of two central systems of the DLR since Spring 2022. The Göttingen system CARO is used mainly for the solution of complex problems in numerical fluid dynamics by DLR researchers from all over Germany. Its sibling, CARA, is hosted by the Centre for Information Services and High Performance Computing (“Zentrum für Informationsdienste und Hochleistungsrechnen” - ZIH) of the TU Dresden.
CARO was the first HPC system installed in the new data center at the Burckhardtweg. It has 1370 nodes with more than 174000 AMD-CPU-cores, more than 370 TB memory and a 8.4 PB storage system. The cluster reached 3.46 PFlops in LINPACK, ranking 135th in the TOP500 list of November 2021.
A team of GWDG members ensures the operation of CARO and provides HPC-support, herein working closely with the CARA-team in Dresden. The cooperation with researchers from the DLR and ZIH is intensified in research and development projects.
The GWDG-team is available for DLR users via different support channels:
- Tickets: Request e-mails to uhd@dlr.de (User-Help-Desk) with "HPC-CARO" at the beginning of the subject line
- Chat: direct communication with the support and other DLR users
- DLR-Wiki: system documentation with commenting possibilities
- User meeting: monthly meetings with talks on different HPC topics
- E-Mail-list: all users receive current information on the system via caro-info@dlr.de
