What accelerated data analytics and computing applied to numerical weather prediction is telling us about the future of supercomputing

Numerical Weather Prediction (NWP) was one of the new domains that emerged in the early days of electronic computing and continues to play a central role in supercomputing today. For almost a decade CSCS and its partners at MeteoSwiss, as well as at the Center for Climate Systems Modelling and the Scalable Parallel Computing Lab of ETH Zurich, have exploited the virtues of accelerated computing and data analytics for NWP and climate modelling. I will share these experiences, as well as the conclusions we have drawn for the design of the “Alps” infrastructure, with which CSCS will be offering future extreme computing and data solutions to support the evolving needs of science.
