Cluster Access

University

Technische Universität Darmstadt

Info

The Lichtenberg Cluster is situated in Darmstadt. It is a tier 2 cluster. Most of the processors are CPU, some accelerators (NVIDIA) are also available.

Note: Phase I of Lichtenberg (Node Type A) is deactivated as of April 2020.

Add. Info

Cluster Introductions:

  • Monthly consultation hours for project proposals, in general every first Wednesday a month.
  • Monthly introductory courses to the Lichtenberg Cluster, in general every second Tuesday a month.
