SUMMARY:FAIR-FLEXI - A Trustworthy CFD Code for Simulation and Training
DESCRIPTION:Engineering and science disciplines\, especially computational fluid dynamics (CFD) generate massive amounts of research data\, but they can only become knowledge if they can be shared and explored through data analytics and AI. This\, in turn\, requires a FAIR (findable\, accessible\, interoperable\, reusable) infrastructure. For complex research software\, however\, FAIR goes far beyond being open-source: reproducibility is hindered by hidden expertise such as user-defined parameters\, compile options\, hardware constraints\, and third-party dependencies.\nThis talk outlines the design\, implementation\, and lessons learned from FAIR-FLEXI. We discuss how comprehensive provenance capture\, portable environments\, and interactive notebooks turn CFD workflows into trustworthy\, reproducible research assets.

SUMMARY:GALAEXI: An Architecture-Agnostic GPU-Acceleration Approach for Legacy Fortran Software
DESCRIPTION: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” \n 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.

SUMMARY:Flagship scientific applications on a European RISC-V long-vector accelerator: Lessons learned
DESCRIPTION:As Europe accelerates its efforts in chip sovereignty\, scientific applications need to be ported to and evaluated on emerging prototypes\, assessing their performance as well as the technology readiness of the new hardware platforms. In this talk\, we will share the experiences and lessons learned when porting applications from CEEC and other Centers of Excellence to the long-vector RISC-V accelerators from the EPI and EUPILOT projects across different domains and applications.\nAttendees will learn code optimization techniques\, common performance pitfalls\, and evaluation methods for long-vector architectures\, which they can apply to their own applications and code bases in order to improve performance on these novel hardware platforms.

SUMMARY:Enabling mixed-precision with VerifiCarlo: Sharing CEEC experience
DESCRIPTION:Join our own Roman Iakymchuk\, Umeå University on behalf of CEEC\, and Pablo de Oliveira Castro\, Université Paris-Saclay UVSQ\, for a 2nd look at VerifiCarlo! \nDriven 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.  \nHowever\, before lowering precision\, one must ensure that the simulation is numerically correct. Verificarlo  is an open-source framework designed to verify and optimize numerical accuracy in complex programs. Built on the LLVM infrastructure\, it provides various floating-point backends to simulate the effects of numerical errors and lower precision. By leveraging alternative floating-point models\, such as Stochastic Rounding\, Verificarlo pinpoints numerical bugs in simulation codes. A probabilistic definition of the number of significant digits allows us to estimate computational accuracy accurately.  \nThrough its variable precision backend\, Verificarlo enables one to explore the trade-offs between precision and performance by simulating lower precisions in software. It identifies specific code regions that benefit from reduced floating-point formats without sacrificing numerical correctness. This approach has been successfully applied in high-performance computing (HPC) domains such as neuroimaging pipelines\, DFT quantum mechanical modeling\, structural simulations\, and now CFD. \nIn 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. \n\n	Notice: JavaScript is required for this content.
