  • Promotional flyer for a webinar titled "Enabling mixed-precision with VerifiCarlo: Sharing CEEC experience." In the top right corner, there is a logo for "CEEC" with a stylized wave design above the letters. Below the title, a blue box provides event details: "March 4, 2024, 10 am - 11 am CET, Online." The box includes a description: "Discover... Verificarlo, An open-source framework for verifying and optimizing numerical accuracy. Learn about Verificarlo’s variable precision backend and that let’s one explore the trade-offs between precision and performance IN neuroimaging pipelines, DFT quantum mechanical modeling, structural simulations, and now CFD." To the right of the blue box is the "Verificarlo" logo, featuring a green checkmark integrated into the letter "V." The background has a subtle wave pattern at the bottom.

    Enabling mixed-precision with VerifiCarlo: Sharing CEEC experience

    Driven by the increasing need to reduce the energy consumption of computing centers and simulations, scientists have begun revising applications, algorithms, and their underlying working/storage precision not just for performance but also for energy efficiency. The goal is to make computational costs sustainable while adhering to the lagom principle—using precision that is “just right” to balance accuracy with efficiency. However, before lowering precision, one must ensure that the simulation is numerically correct. Verificarlo is an open-source framework designed to verify and optimize numeric aaccuracy in complex programs. In this webinar, we will introduce Verificarlo, showcase its backends for numerical bug detection and mixed-precision analysis, and present a success story highlighting the road from analysis of codes with Verificarlo to reliable mixed-precision codes.

  • 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.

    In this webinar we’ll provide an overview of the DLB library and each one of its modules. For each module we’ll share its main features, how to use it, and some success stories. We’ll put special focus on the TALP module and its recent extension to provide GPU metrics when getting performance measurements.

  • Announcement poster for a webinar titled "Exploring CI/CD Tools and Workflows for Research and HPC Software Projects". The CEEC logo appears in the top right corner. The main content is in a white rounded rectangle with a curled-corner effect and a drop shadow. Text on the poster: "Exploring CI/CD Tools and Workflows for Research and HPC Software Projects CEEC Continuous Integration and Continuous Deployment (CI/CD) are essential for sustainable and reproducible software development, yet many projects still lack a structured workflow. This webinar provides a beginner-friendly introduction to CI/CD with a focus on EuroHPC. We will explore why CI/CD matters, review a selection of tools commonly used or even developed within European projects, and discuss their strengths, limitations, and typical use cases. The goal is to help developers new to CI/CD understand available options and how to choose tools that fit their needs. November 26, 2025 14:00 – 15:00 CET Online" Visuals: Modern, minimalist design with black text on a white background. There are three small icons at the bottom left: a calendar, a clock, and a location pin next to the corresponding event details. The bottom of the poster is decorated with blue wavy lines as a subtle graphic element.

    Exploring CI/CD Tools and Workflows for Research and HPC Software Projects

    Online

    Continuous Integration and Continuous Deployment (CI/CD) are essential for sustainable and reproducible software development. This webinar provides a beginner-friendly introduction to CI/CD with a focus on the EuroHPC community. We will explore why CI/CD matters, review a selection of tools commonly used or even developed within European projects, and discuss their strengths, limitations, and typical use cases. A short example from the waLBerla project will illustrate how such workflows can be applied in practice.

  • Poster for a webinar titled "Performance Portability for Fortran CFD Software with GALÆXI." At the top left, bold black text displays the title. The top right features the CEEC and GALÆXI logos. Main section text: "Join CEEC and Spencer Starr for a webinar on porting Fortran codes with CUDA/HIP C++! We’ll discuss important design questions and porting requirements (e.g. adapting algorithms and data structures) through the example of the high-order discontinuous Galerkin spectral element CFD code GALÆXI." Date and time information with icons: December 9, 2025, 14:00 – 15:00 CET, Online. Simple white and grey background with a thin, curled-corner border around the main text and a subtle wave pattern at the bottom.

    Performance Portability for Fortran CFD Software with GALÆXI

    Online

    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 taking a Fortran CFD code and porting it to GPUs using CUDA/HIP C++. We will cover the basics of GPU hardware and programming through the example of the high-order discontinuous Galerkin spectral element CFD code GALÆXI, including the important design questions and porting requirements for researchers to consider when porting their own codes.
