... but time flies!

and a new supercomputer is needed.

and transformers: big boxes, smaller boxes and the first GPU...

The directors and producers had not only the duty to find components  to transform to a GPU-Cluster and to fight for money but additionally to find electric power, fortunately only half the electric power for seven times more computing power. And finally the project could get started in a high security area of the university computer center...   

The project is realized together with sysGen Gmbh (a supplier for computer engineering) and NVIDIA (a leading producer of GPUs).
The content of a lot of smaller and bigger boxes has to be filled into 14 racks. In the end there will be 224 GPUs with a processing power of 3.5 Petaflops.
