High Performance Computing
The series of Lichtenberg high-performance computers at TU Darmstadt provides computing resources for researchers from academia and public research facilities in Germany. The multifaceted architecture of the high performance computer allows for flexible and efficient scientific computing, especially for computationally intensive applications.
Film: The Lichtenberg II with focus on performance and energy efficiency
The new high-performance computer Lichtenberg II includes large memory nodes (this time with 1.5 TByte RAM), as well as new “accelerator” systems with dedicated NVIDIA GP-GPUs. Further, an expansion in the form of several “DGX A100” systems is currently underway, which will support modern AI research. Learn more in our film!
The first expansion stage
The first expansion stage of Lichtenberg II provides its users with a real peak performance of over 3,148 PFlop/s and a total of 257 TByte RAM. This also includes a new high-performance storage system with around 4 PByte for data, most of which has already been operational in 2019.
Second expansion stage
Currently in the process of acquisition and configuration is the second large expansion stage, delivering more computing power, additional accelerator systems and again a new storage system. Here, all the same a major focus is on energy-efficient operations and waste heat recovery.
Funded by the German Federal Government and the State of Hesse
The entire Lichtenberg II system (all expansion stages) is funded by the German Federal Government and the State of Hesse with a total amount of ~15 million euros.
The experts of the “Hessisches Komptenzzentrum für Hochleistungsrechnen” (Hessian Competence Center for High Performance Computing) will provide for consultancy and scientific support on using the cluster efficiently and hosts various workshops on scientific HPC.
