New Scientific Paper: Prediction model of performance–energy trade-off for CFD codes

When on a long distance car trip, do you prioritise speed or fuel efficiency? For most cars, maximum fuel efficiency is achieved at a speed of between 50-80km/h. Travel any faster and you will consume more fuel to reach your destination. Work with computational fluid dynamics (CFD) codes on high performance computing (HPC) architectures faces

Scaling to new heights: Xyst code excites with unprecedented 196K core run on LUMI supercomputer

In what may prove to be a significant milestone in High Performance Computing (HPC), researchers with HiDALGO2 have demonstrated the potential of a new code called Xyst to run efficiently on almost 200,000 CPU cores in parallel. While further validation is necessary, early results are promising and indicate that Xyst may allow certain complex modelling
