Extreme-Scale High-Fidelity Computational Fluid Dynamics with Neko
2025-10-22 14:00 - 15:00 (Europe/Paris) | Online
Neko is a portable framework for high-order spectral element-based simulations, mainly focusing on incompressible/compressible flow. The framework is written in a modern object-oriented approach and supports various hardware backends, ranging across general-purpose processors, accelerators, and vector processors. Neko has demonstrated excellent performance and scalability across various hardware architectures and was nominated as a finalist for the ACM Gordon Bell prize in 2023.
In this webinar, we will provide an introduction to Neko and its capabilities, from installation to creating and running simulations. Special focus will also be on the major changes in terms of features and functionalities, user interaction, and improvements made in the upcoming release of Neko v1.0. By the end of the webinar, attendees will have a basis as well as references and materials to start working with Neko on their own time.

Exploring CI/CD Tools and Workflows for Research and HPC Software Projects
2025-11-26 14:00 - 15:00
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. A short example from the waLBerla project will illustrate how such workflows can be applied in practice.

Performance Portability for Fortran CFD Software with GALÆXI
2025-12-09 14:00 - 15:00
With GPU acceleration now ubiquitous in HPC, there is more pressure than ever to port existing simulation software to leverage the new hardware. There are many GPU programming models available, but they often have limited, or completely lack, support for Fortran. This leads owners of existing Fortran scientific codes to struggle with porting their software to multiple computing architectures. One option is to turn to C++ to achieve the greatest performance portability.
This webinar is a guide for the process of taking a Fortran CFD code and porting it to GPUs using CUDA/HIP C++. The basics of GPU hardware and programming will be covered, to serve as a rough guide for adapting algorithms and data structures. The high-order discontinuous Galerkin spectral element CFD code GALÆXI is then presented. The important design questions and porting requirements in GALÆXI are discussed, which researchers must answer and understand to effectively port their own Fortran codes with CUDA/HIP C++.
