The Hessian universities provide high performance computers of different performance classes.
In Hesse, the clusters Lichtenberg II (Darmstadt) and Goethe-HLR (Frankfurt) are suitable for medium and large jobs and are available for all researchers in Germany.
The clusters in Giessen, Kassel, and Marburg suit medium and small jobs.
Furthermore, TU Darmstadt is part of the NHR alliance, which provides compute ressources of medium and large capacity for all of Germany.
Even more computational power can be applied at the national Gauß-Center for Supercomputing.
