🎓 3rd ESiWACE3 Hackathon

On 21–23 October 2025, the 3rd ESiWACE3 Hackathon will take place at the Jülich Supercomputing Centre (JSC) in Jülich, Germany. Titled “Porting Earth System Models to the First EuroHPC Exascale System (JUPITER),” this event supports researchers and developers preparing their Earth System Models (ESMs) for Europe's first exascale supercomputer.

The hackathon will be hybrid, with in-person participation strongly encouraged. At least one team member must attend in person, though others may join remotely if needed.

Participants will bring their code and collaborate with High-Performance Computing (HPC) experts to optimize and port climate and weather models for JUPITER, featuring NVIDIA GH200 Grace Hopper Superchips. The focus areas include performance optimization, portability, and scalability on exascale systems.

Eligible applicants must be from EuroHPC Joint Undertaking or Inclusiveness Target Countries. Teams of two to four members, with a mix of expertise in Earth system modeling and HPC, are encouraged to apply. Preference is given to open-source projects and early-career scientists.

Teams must submit a short proposal outlining their project, challenges, and expected outcomes. The application deadline is 30 June 2025, with notifications by 15 July 2025.

A €1500 prize, sponsored by HPC services provider Do It Now, will support the winning team’s attendance at a European academic conference.
