At TU Darmstadt, the Lichtenberg High Performance Computer provides computing resources for scientific research for scientists of different Hessian universities.

The multifaceted architecture of the high performance computer allows for flexible and efficient scientific computing, especially for computationally intensive applications. It supports the efficient execution of a variety of existing programs, as well as the development of new parallel programs.

The experts of the “Hessischen Kompetenzzentrum für Hochleistungsrechnen” (Hessian Competence Center for High Performance Computing) will provide for consultancy and scientific support on using the cluster efficiently. The HKHLR also hosts various (regular) workshops on scientific HPC.

The high performance computer has been established in two phases. The first phase has already been installed in 2013, the second phase was installed 2015. In total, the two phases comprise of about 1400 nodes, 35 times the computing power of the old cluster (“HHLR”). In its current configuration, the Lichtenberg cluster has a theoretical peak performance of approximately 1 PFLOP/s.

Funding for the acquisition and and operation is provided by TU Darmstadt, the state of Hesse and the German Federal Government.

Further information can be found under Access, Cluster Usage and Service.
