In the context of the Cosmic dawn Project, the French National Jean Zay’s supercomputer (rated at 28 hybrid peak Peta-FLOPS and more than 330 peak GPU Tensor Peta-FLOPS), owned by GENCI, hosted and operated by IDRIS/CNRS has allocated 1.7 million hours computing resources to the LICORICE simulation project.

The observations are processed on a dedicated compute-cluster called Dawn (http://www.aspbooks.org/a/volumes/article_details/?paper_id=39880), which consists of 48 × 32 hyperthreaded compute cores and 4 x 32 Nvidia K40 GPUs distributed over 32 nodes. The cluster is located at the Centre for Information Technology of the University of Groningen.
