At the C²A²S²E simulation centre (Centre for Computer Applications in AeroSpace Science and Engineering) in Braunschweig, a high-performance computer for aeronautics research has been brought into use by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) today. This computer is the core of the simulation centre and it is Europe’s fastest high-performance computer for aeronautics research. Every second, it computes a set of numbers large enough to fill a pile of CDs over 600 metres tall with data. This new supercomputer for aeronautics research is operated by T-Systems. The C²A²S²E simulation centre is an innovative partnership between Airbus, the federal state of Lower Saxony, and the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR).
