The Lichtenberg Cluster is a tier 2 cluster. Most of the processors are CPU, some accelerators (NVIDIA) are also available.
The Lichtenberg II Cluster, like its predecessor, is a high-performance computer in the medium performance class (tier 2). It has a heterogeneous architecture including large memory nodes, accelerator systems with dedicated NVIDIA GPUs, and several DGX A100 systems to support modern AI research.
The series of Lichtenberg high-performance computers provide 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. The experts of the “Hessischen Komptenzzentrum für Hochleistungsrechnen” (Hessian Competence Centre for high-performance Computing) will provide for consultancy and scientific support on using the cluster efficiently and hosts various workshops on scientific HPC. The new high-performance computer Lichtenberg II includes large memory nodes (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.
The first expansion stage (including last year's expansion) of Lichtenberg II will in future provide 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 is operational since 2019. By the end of 2021, the Lichtenberg II high-performance computer will be finally extended and completed by its second major expansion stage.
Furthermore, the new cluster expansion stage not only offers high computing power, but is also operated very energy-efficiently.
