  • VPREC to analyze the precision appetites and numerical abnormalities of several proxy applications

    The third in a series of presentations from Roman Iakymchuk on work using tools to investigate mixed precision possibilities. He and his co-author Pablo de Oliveira Castro introduce an approach to address the issue of sustainable computations with computer arithmetic tools. They use the variable precision backend (VPREC) to identify parts of code that can benefit from smaller floating-point formats and show preliminary results on several proxy applications.

  • Introduction to Computational Fluid Dynamics

    HLRS University of Stuttgart Nobelstraße 19, Stuttgart, Germany

    Join our Anna Schwarz as one of the instructors for the reoccuring “Introduction to Computational Fluid Dynamics” course organized by HLRS, IAG (University of Stuttgart) and the
    Institute of Software Methods for Product Virtualisation (DLR).

  • A promotional graphic for the CASTIEL code of the month "FLEXI/GALÆXI: Open-Source Solver for Multiscale Flows." The text includes "Code of the Month Vol. 11, October 30th, 2024" and "Speakers: Anna Schwarz, Centre of Excellence in Exascale CFD (CEEC)." The background features an abstract design with a large circle on the left, displaying a gradient of colors from blue to orange, suggesting multiscale flows. The bottom right corner displays the words "FLEXI GALÆXI" in bold letters.

    FLEXI/GALÆXI: Open-Source Solver for Multiscale Flows

    Join us for the 11th CASTIEL Code of the Month to learn about FLEXI/GALÆXI!
    Both solvers provide a high-order consistent simulation tool chain for solving the compressible Navier–Stokes equations in a highly efficient, accurate and robust manner in a high performance computing setting either on CPU-based systems (FLEXI) or GPUaccelerated clusters (GALÆXI).

  • GALEXI: Scale-resolving simulations of compressible turbulence on GPU-accelerated systems

    Room 9

    Joine our Anna Schwarz for her talk “GALEXI: Scale-resolving simulations of compressible turbulence on GPU-accelerated systems”, part of the workshop “Tackling Software Exascale Challenges: the Centres of Excellence in High-Performance Computing Perspective”. She will present GALEXI, the GPU version of FLEXI, and the grogress she’s made in CEEC preparing these codes for exascale CFD simulations.

  • CEEC at ISC25

    Join our own Niclas Jansson at the Euro HPC JU booth for a presentation on our project and progress so far!
