AMD announced that its EPYC processors have been selected by the European Centre for Medium-Range Weather Forecasts (ECMWF) to accelerate its new supercomputer, based on Atos’s latest BullSequana XH2000 technology, for one of the most powerful meteorological supercomputers in the world. Once operational in 2021, the supercomputer will allow ECMWF to run its predictions at a higher resolution, of around 10km, offering reliable, advanced numerical predictions about the occurrence and intensity of extreme weather events ahead of time. The increase in ECMWF’s computing power, with the industry leading core count of the AMD EPYC™ 7742, will support hundreds of researchers from over 30 countries across Europe in their work on medium and long-range weather forecasting. Based in Reading in the UK, ECMWF is an independent intergovernmental organization supported by 34 Member and Co-operating States across Europe and holds the largest archive of numerical weather prediction data in the world. The system will be delivered and installed at the ECMWF data centre in Bologna, Italy in 2020, with service commencing in 2021. Atos will work locally with E4 Computer Engineering to manage, run and maintain the system.
