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.

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.

A person with short hair stands in front of large windows, silhouetted against the light, with a backpack on their back. The view outside includes a cityscape. Two digital displays are visible. The left display, titled "POP," features a flowchart or diagram with text and icons. The right display, titled "CEEC," contains text and graphs, resembling an informational poster. Outside, a road with a bus and distant buildings is visible under a partly cloudy sky.
