CSCS - Swiss National Supercomputing Centre EMPA/daint#

Description#

Platform plugin for the CSCS Piz Daint supercomputer — used by EMPA.

Deprecated since version Piz: Daint was decommissioned in December 2023 and replaced by the CSCS Alps system. This plugin is kept for reference and for users who may still have access to archived runs.

The Piz Daint system at the Swiss National Supercomputing Centre (CSCS) was a Cray XC50/XC40 hybrid system. EMPA (Swiss Federal Laboratories for Materials Science and Technology) used this system for atmospheric inversion work.

Job submission uses sbatch (SLURM); environment modules are managed by Lmod via a tcsh modulecmd.
