SUMMARY:Neko – a European code development effort shortlisted for the 2023 ACM Gordon Bell Prize
DESCRIPTION:Come listen to our own Niclas Jansson talk about his work on NEKO\, which has been shortlisted for the 2023 ACM Gordon Bell Prize. We have the great fortune of being able to build on this work during the cEEC project. Learn more in his interview at the LUMI stand (booth 206)!

SUMMARY:Exploring the Ultimate Regime of Turbulent Rayleigh–Bénard Convection through Unprecedented Spectral-Element Simulations
DESCRIPTION:Don’t miss the official presentation of the work on NEKO that is nominated for the Gordon Bell Prize! \nOfficial Description: We detail our developments in the high-fidelity spectral-element code Neko that are essential for unprecedented large-scale direct numerical simulations of fully developed turbulence. Major innovations are modular multi-backend design enabling performance portability across a wide range of GPUs and CPUs\, a GPU-optimized preconditioner with task overlapping for the pressure-Poisson equation and in-situ data compression. We carry out initial runs of Rayleigh–Bénard Convection (RBC) at extreme scale on the LUMI and Leonardo supercomputers. We show how Neko is able to strongly scale to 16\,384 GPUs and obtain results that are not possible without careful consideration and optimization of the entire simulation workflow. These developments in Neko will help resolving the long-standing question regarding the ultimate regime in RBC.
