University
Technische Universität Darmstadt
Info
Like its predecessor, the successor to the Lichtenberg cluster 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 GP-GPUs and several DGX A100 systems to support modern AI research.
