9th ENES HPC Workshop

The event was hosted by the  Swedish Meteorological and Hydrological Institute (SMHI) and organized by the European Center of Excellence for Weather and Climate Simulation in Europe (ESiWACE3). This biennial workshop has established itself as an important meeting place within the European Network for Earth System Modelling (ENES) and beyond, fostering collaboration between modeling centers, HPC facilities, and technology providers across Europe and internationally.

This time, experts from the European weather and climate modeling community discussed current developments in high-performance computing, data infrastructures, and the use of artificial intelligence for Earth system modeling.

In four thematic sessions, participants exchanged views and presented activities on European and international collaboration, performance and accelerator technologies, AI and machine learning applications, and challenges in data management. Two of these sessions were organized or co-organized by Jochim Biercamp and Karsten Peters-von Gehlen(both DKRZ). Discussions covered topics such as digital twins, GPU porting, scalable model development, neural prediction systems, hybrid AI approaches, and large-scale climate data workflows.

A central cross-cutting theme throughout the workshop was the importance of co-design between the scientific, software, and hardware communities to enable the next generation of AI-powered kilometer-scale climate and weather models.

In addition, researchers from the DKRZ contributed three presentations addressing model performance, cloud storage based workflows, and kilometer-scale simulations:

• Hendryk Bockelmann gave a presentation titled “ICON everywhere and for everyone – efficiency and challenges.” The presentation focused on approaches to improving the user-friendliness and efficiency of the ICON model in various computing environments.
• Fabian Wachsmann presented the concept of the “EERIE Cloud” and its applications for immediate and efficient high-resolution climate data access. 
• Using the WCRP Global Hackathon as an example, Florian Ziemen’s presentation titled “km scales hacked at global scale” addressed challenges and current progress related to interactive access to and analysis of kilometer-scale simulations.
