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.

Add. Info

Cluster introductions:

  • Monthly consultation hours for the preparation of project proposals for the use of the cluster: usually every first Wednesday of the month.
  • Monthly introduction to the use of the cluster: usually every 2nd Tuesday of the month.
