Owing to the continued Covid-19 situation the DeepRain partners have now adopted a monthly schedule for online meetings. For specific technical and scientific discussions, smaller teams meet weekly. Over the past month, at JSC the data import of the COSMO ensemble weather model have been improved, and the benchmarking tests regarding data entry and data extraction has been successfully completed. New instances of the Rasdaman array databases (“data cubes”) have been installed on JSC resources, including one instance of the Rasdaman Enterprise server, which will soon become a node in an international data federation. The JSC team further supported Osnabrück with their implementation of machine learning workflows on the Jülich supercomputer systems.
