picture of amplitUDE in 2024

In 2024 the next high-performance computing system amplitUDE has put into operation.

The main funding for the procurement of the system was realised under the leadership of Prof. Dr. Jörg Schröder with other UDE researchers in cooperation with the Center for Computational Sciences and Simulation (CCSS) and the Centre for Information and Media Services (ZIM) within the framework of the DFG program “Forschungsgroßgeräte nach Art. 91b GG” (DFG INST 20876/423-1 FUGG).

Supplier: MEGWARE GmbH
