Center of Excellence in Exascale CFD (CEEC)

A promotional graphic for a CEEC webinar. The background is white with a subtle wave pattern at the bottom. Top left: the title “Extreme-Scale High-Fidelity Computational Fluid Dynamics with Neko” in large bold black text. Top right: the CEEC logo, with a small wave above the first “C.” Center left: a white scroll-like box with curled corners containing the text: “Join CEEC and Niclas Jansson for a webinar introducing Neko and its upcoming improvements! Learn about major feature changes, user interaction, and updates in Neko v1.0.” Below are icons with info: calendar – “October 22, 2025”; clock – “14:00–15:00 CET”; location pin – “Online.” Right side: the NEKO logo with bold, slanted text and a cartoon cat face with goggles and a swirling wave under its chin. The monochrome design uses clean lines and a technical, modern style.

🌊 Join CEEC + @njansson.bsky.social on Oct 22 (14:00–15:00 CET) for a webinar on @neko.cfd, a high-order framework for large-scale CFD. Learn what’s new in v1.0, from setup to extreme-scale performance.

Group photo of the CEEC consortium taken during their project review in Luxembourg. Fourteen people stand together in a modern conference room, with a German Shepherd guide dog and her handler positioned near the left. The group is dressed in business or business casual clothing, with conference tables, laptops, and a large screen displaying a "WP3 – Exascale Algorithms" slide with the CEEC logo in the foreground. One person is holding an EU flag, highlighting the project's European context.

✨ Greetings from Luxembourg!
Our review brought strong, supportive feedback that sharpens our path in exascale CFD.

Huge thanks to our reviewers for their time, insights & encouragement — your guidance is invaluable!

Poster titled “Introduction to the DLB Library and Measuring GPU performance” at the top in bold black font. To the right of the title are two logos: one for dynamic load balancing (with a blue icon resembling test tubes) and one for CEEC (black bold letters). Below the title is a white speech-bubble shaped text box with the following text: Join CEEC and Marta Garcia for a webinar introducing the Dynamic Load Balancing (DLB) library and its modules! We’ll share each module’s main features and how to use them, with extra focus on the new TALP GPU metric collection feature. Below this paragraph are three icons with corresponding event details: • A calendar icon next to: September 17, 2025 • A clock icon next to: 15:00 – 16:00 CET • A location pin icon next to: Online To the right of the main text is a rectangular photo of Marta Garcia speaking on stage with a microphone, in front of a presentation slide. She wears a striped shirt, and the background slide includes anatomical heart graphics and headshots. Below the main text box is a slightly tilted image of a diagram. It shows a white 3D figure typing on a laptop labeled "Program App.", pointing to a blue arrow labeled "Run with DLB", followed by charts and cloud-like graphics suggesting performance improvement. The DLB logo appears again in this diagram. The bottom of the poster features stylized wave lines in blue and gray.

Two individuals wearing 3D glasses stand in an immersive virtual reality environment filled with a 3D projection of orange spheres and blue arrows, creating a tunnel-like effect. They are interacting with the visualization using handheld devices. A menu with options such as "move," "scale world," and "navigation" is visible on the right side, indicating a control interface for the virtual environment. The scene is vibrant and dynamic, focusing on data visualization.
