hpc4climate 2025 Summer School starts today!

Today, we’re proud to launch the hpc4climate 2025 Summer School, bringing together a 30 master and doctoral students to explore the powerful intersection of high-performance computing (HPC) and climate science.

Hosted in Lauenburg, the summer school has drawn talented participants from across Europe and beyond — with backgrounds in computer science, applied mathematics, physics, meteorology, and environmental sciences. As they arrive, the excitement is palpable: ten days of immersive learning about climate models and, in particular, ICON, collaboration, and innovation lie ahead.

This initiative is part of the WarmWorld project, supported by the EuroHPC-JU ESiWACE3 Project, and co-sponsored by DKRZ and the Max Planck Society. The program aims to build capacity in the next generation of climate modelers, particularly by promoting diversity, inclusion, and excellence in technical fields often underrepresented in climate science.

Throughout the school, participants will:

• Gain practical experience working with the ICON climate model
• Learn key HPC and software engineering skills for Earth system science
• Explore cutting-edge methods in data analysis, parallelization, and scientific computing
• Engage in coding labs, tutorials, and team challenges designed around real-world research problems

Coding challenges will cover topics ranging from heterogeneous computing environments (including GPU/CPU architectures) to open-source software workflows, and from numerical modeling to visualizing simulation outputs.

We’re honored to open the summer school with a keynote lecture by Prof. Florina Ciorba (University of Basel), a leading voice in scalable and energy-efficient computing for scientific applications. Her talk will provide crucial insights into the challenges and opportunities in HPC for natural sciences and climate modeling — setting the stage for a week of technical deep-dives and interdisciplinary exchange.

Beyond the technical content, hpc4climate 2025 is also about community. By connecting early-career scientists with peers, mentors, and leading researchers in the field, we hope to foster a vibrant network of changemakers who will carry forward the mission of building better, faster, easier and smarter climate science.

Stay tuned as we share updates, photos, and reflections from the week. And to all our participants: welcome, and thank you for being part of this important journey!
