The high-performance computing network of the German Aerospace Center (DLR) is a basis and a tool to, for example, accelerate the introduction of new technologies for more economical, environmentally friendly and safer flying – while ensuring better control of technology-related risks. It has many other potential applications in the aeronautics and space sectors, as well as in energy and ground-based transport.
Three quadrillion computations per second
The performance of the CARA cluster in Dresden, which began operation in 2019, is already equivalent to that of about 10,000 standard personal computers. Expansions planned for 2020 in Dresden (by approximately 25 percent) and Göttingen (by approximately 60 percent), will take the capacity of the DLR high-performance computing network to well over three petaFLOPS. This means that the network will be able to perform over 3,000,000,000,000,000 calculations per second, making it the biggest facility of its kind in Europe to be used almost exclusively for aerospace applications.
This large-scale facility is vital for the implementation of ambitious DLR projects such as the virtual (i.e., solely computer-created) aircraft. Among other things, it is intended to enable the future certification of aircraft by computer. The complex, high-precision simulations necessary for developments in future space transport or next-generation trains can only be generated with computing power on this scale.
