DKRZ, the German Climate Computing Centre, provides state-of-the-art supercomputing and data service infrastructure to the German and the international climate research community. More than 1000 national and international scientific users use the technical infrastructure of DKRZ to generate, process, analyse and visualise of huge amounts of data in the context of climate research.

As important as providing the infrastructure for research, DKRZ delivers general user support and specific support for problems related to scientific computing: here DKRZ benefits from its role as acknowledged HPC expert especially in the field of code optimisation and parallelisation and participates in many national and international projects.

Role in the project

In ESiWACE2, DKRZ coordinates the project in WP7 (Coordination, Management and Dissemination). This includes the scientific and administrative responsibility for the work of the consortium, ensuring an effective and smooth implementation of the project, and dissemination of ESiWACE2 results and achievements.

Moreover, DKRZ co-leads WP1 (Production runs at unprecedented resolution on pre-exascale supercomputers) and WP5 (Data Post-Processing, Analytics and Visualisation), work packages that benefit from the role of DKRZ as interface between scientific and technical communities.

Apart from this, DKRZ contributes to WP2 (Establish, evaluate and watch new technologies for the community), WP3 (HPC services to prepare the community for the pre-exascale), WP4 (Data systems for scale) and WP6 (Community Engagement and Training).

Relevant infrastructure and services available for climate & weather

DKRZ operates Levante, one of the largest supercomputers in Germany comprising 2,832 computing nodes equiped with two AMD EPYC processors each (more than 360,000 cores in total), which deliver a total peak computing performance of 14 petaFLOPS. Moreover, Levante is equipped  with a storage system of approx. 130 Petabytes manufactured by DDN. In summer 2022, DKRZ’s supercomputer gets extended by a partition of 60 GPU nodes delivering a peak performance of 2.8 PetaFLOPS.

With respect to data services, DKRZ operates the ICSU World Data Center for Climate with more than 550 TB fully documented climate data and field-based data access. DKRZ is a non-profit and non-commercial limited company and participates in many national and international projects related to climate modeling.
