CEEC Progress Towards more energy-efficient CFD
Energy efficiency is a growing challenge in high-performance computing as systems become more powerful and complex. We analyzed energy use across major European supercomputers using CFD applications, highlighting how GPUs and mixed-precision methods can reduce energy consumption while maintaining performance and accuracy.

FAIR-FLEXI – A Trustworthy CFD Code for Simulation and Training
Engineering and science disciplines, especially computational fluid dynamics (CFD) generate massive amounts of research data, but they can only become knowledge if they can be shared and explored through data analytics and AI. This, in turn, requires a FAIR (findable, accessible, interoperable, reusable) infrastructure. For complex research software, however, FAIR goes far beyond being open-source:…

Performance Portability for Fortran CFD Software with GALÆXI
With GPU acceleration now ubiquitous in HPC, porting existing simulation software to leverage GPUs is more important than ever. Although many GPU programming models exist, they often have limited or no support for Fortran, making porting existing Fortran scientific codes to multiple computing architectures an extra struggle. This webinar guides you through one solution of…

CEEC at EuroHPCSummit2025
We ahad the pleasure of joining over 30 other EuroHPC Joint Undertaking funded projects developing skills, codes, technologies, and even international cooperation in the poster showcase at last week’s #EuroHPCSummit2025 in Krakow, Poland. As we enter the second half of our project runtime, we chose to showcase the scaling results of our codes so far.…
