ESiWACE3 had a strong presence at ISC High Performance 2026, one of the world’s leading conferences on high-performance computing, where the project showcased its latest achievements in weather and climate simulation to the international HPC community.

The project participated in the Project Poster Reception, where Erwan Raffin (Bull) presented ESiWACE3: The Centre of Excellence in Simulation of Weather and Climate in Europe. The session provided an excellent opportunity to engage with researchers, developers and industry representatives, exchanging ideas on the latest advances in high-performance weather and climate modelling.
ESiWACE3 was also featured at the EuroHPC Joint Undertaking Booth J30 Presentation Corner, where visitors learned more about the project’s activities, achievements and contribution to the European HPC ecosystem.
Beyond these outreach activities, ESiWACE3 research was highlighted during two technical workshops at ISC:
- Arm HPC User Group (AHUG) Workshop, where project results on co-design were presented.
- Readiness of HPC Extreme-scaling Applications (RHEA) Workshop, featuring ESiWACE3 work on co-design methodologies for next-generation HPC systems.
Reflecting on the event, Erwan Raffin commented:
“It was a great pleasure to showcase the ESiWACE3 project and its results during ISC 2026. It was the perfect place to meet and exchange ideas with many members of the HPC community.”
Throughout the conference, the project team engaged with researchers, software developers and technology experts from academia and industry, discussing topics ranging from weather and climate models to compiler technologies and HPC software ecosystems.

ESiWACE3’s participation at ISC 2026 reinforced the project’s commitment to advancing high-performance weather and climate simulation while fostering collaboration across the European HPC community.
