  • ‘Enabling mixed-precision with the help of tools: A Nekbone case study’ at PPAM24

    Ostrava, Czechia Ostrava, Czech Republic

    If you’re going to PPAM24 September 8 – 11 in Ostrava, Czechia, make sure to check out the talk by Yanxiang Chen from our partner UMU on their progress implementing and optimizing mixed precision in Nekbone toward its integration in Neko and NekRS. The accompanying paper is also available as a pre-print online: https://arxiv.org/pdf/2405.11065

  • CEEC at ISC25

    Join our own Niclas Jansson at the Euro HPC JU booth for a presentation on our project and progress so far!

  • Promotional graphic for a webinar titled “Extreme-Scale High-Fidelity Computational Fluid Dynamics with Neko.” The title is written in large bold black letters across the top left on a white background. In the top right corner is the CEEC logo in black, with three curved lines above the first “E” suggesting airflow. Below the title, inside a rounded white rectangular panel with a thin black outline, is the event description in black text: “Join CEEC and Niclas Jansson for a hands-on webinar introducing Neko! We’ll explore Neko's capabilities, focusing on major updates to its features, functionalities, and user interaction. This interactive session will teach participants how to run the code and fine-tune configuration settings for peak performance.” Near the bottom left of the panel, small black icons show a calendar, a clock, and a location pin, followed by the event details: “June 17, 2026 13:00 – 15:00 CEST Online” On the right side of the image, outside the text panel, is the Neko logo: a stylized black-and-white cartoon cat wearing goggles, with a curved, wave-like flourish beneath it, followed by the word “NEKO” in bold, italicized, horizontal-striped letters that give a sense of motion. Along the very bottom edge of the image, thin gray wavy lines suggest flowing fluid or waves.

    Extreme-Scale High-Fidelity Computational Fluid Dynamics with Neko

    Neko is a portable framework for high-order spectral element-based simulations, focusing primarily on incompressible and compressible fluid flows. Written using a modern object-oriented approach, the framework supports a wide range of hardware backends, including general-purpose processors, accelerators, and vector processors. Neko has demonstrated excellent performance and scalability across various hardware architectures and was nominated as […]

  • Mixed-Precision and Energy-Efficiency in SEM Codes

    Congress Center Hamburg Congressplatz 1, Hamburg, Germany

    Mixed-precision computing has emerged as a key strategy to improve performance and energy efficiency on current and future high-performance computing (HPC) systems. However, integrating mixed-precision into large, production-level scientific applications remains challenging due to concerns about numerical stability, accuracy, and the complexity of identifying which computations can safely tolerate reduced precision. Our results confirm that mixed-precision approaches, when carefully designed and guided by arithmetic and performance analysis, can yield significant improvements on HPC platforms for real-world scientific applications.

  • Presenting CEEC at ISC

    Congress Center Hamburg Congressplatz 1, Hamburg, Germany

    Join our own Niclas Jannson at the EuroHPC JU booth J30 for an overview of CEEC and our progress. You’ll have a chance to ask questions and learn what CEEC work could mean for you and the future of CFD.

  • CEEC at WCCM – ECCOMAS 2026

    Join us in Munich for the 17th World Congress on Computational Mechanics 10th European Congress on Computational Methods in Applied Sciences and Engineering (WCCM – ECCOMAS 2026 ) for a talk called, “Adjoint Methods Using POD State Reconstructions on Modern HPC Architectures.”

    Part of the mini-symposium MS349B Topology, Shape And Parameter Optimisation For Time-Dependent Systems II, the talk given by our own Harrison Nobis discusses the potential for placing checkpointing with Proper Orthogonal Decomposition to make adjoint sensitivity analysis in CFD more efficient and better suited to modern heterogeneous architectures.

  • Digital event flyer titled “From Lighthouse Cases to Exascale Practice: Outcomes of CEEC,” with the CEEC logo at the top right. A large white scroll-shaped box on the left contains black text inviting people to CEEC’s last community workshop, explaining that they will present achievements from six lighthouse cases in aeronautics, energy, process engineering, shipping, and atmospheric flows, along with transferable knowledge, tools, and methods for high-fidelity CFD and European HPC. Below the text, icons indicate the event details: calendar icon followed by “November 10, 2026”; clock icon followed by “13:00 – 15:00 CEST”; location pin icon followed by “Online or Stockholm.” On the right side, there is a teal-to-blue gradient rectangle with the CEEC logo: the letters “CEEC” in large white capitals with three curved wave lines above the first “C,” and the subtitle “Centre of Excellence in Exascale CFD” below in smaller white text. Wavy blue lines run along the bottom edge of the flyer as a decorative element.

    From Lighthouse Cases to Exascale Practice: Outcomes of CEEC

    Online or KTH Center for Scientific Computing (KCSC) Teknikringen 14, Stockholm, Sweden

    Since 2023, the Center of Excellence in Exascale CFD (CEEC) has worked to make high-fidelity CFD ready for Europe’s exascale systems. Its work has been driven by six lighthouse cases, addressing challenges from aeronautics, offshore energy, process engineering, shipping, and atmospheric flows, chosen to push physics and software to their limits. This community workshop presents what those cases have delivered, and is meant for CFD practitioners, code developers, HPC centers and industry users who want to see what exascale CFD delivers today, and where it goes next.
