Exploring CI/CD Tools and Workflows for Research and HPC Software Projects
2025-11-26 14:00 - 15:00 (Europe/Paris) | Online
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 | Online
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++.

GALAEXI: An Architecture-Agnostic GPU-Acceleration Approach for Legacy Fortran Software
2026-03-03 18:25 - 18:50
Join Spencer Starr at the Society for Industrial and Applied Mathematics (SIAM)Processing for Scientific Computing (PP26)confrence in Berlin for his talk on “GALAEXI: An Architecture-Agnostic GPU-Acceleration Approach for Legacy Fortran Software”
GALAEXI is a high-order discontinuous Galerkin spectral element method (DGSEM) computational fluid dynamics (CFD) code used for the study of compressible, turbulent flows. It is the device-accelerated version of an existing Fortran-based, CPU-only CFD framework. In this talk, the chosen strategy for porting the Fortran-based compute kernels in GALAEXI to CUDA/HIP C++ is covered. Included are discussions on managing device memory, retaining support for CPU computations, strategies for writing and testing kernels and how to handle GPU-to-GPU MPI communication. Specific emphasis is placed on how the strategies covered can be abstracted in an architecture-agnostic way to allow the greatest degree of portability. The information presented will then be distilled into advice for those seeking to perform a similar porting effort.
