The ESCAPE project : Energy-efficient Scalable Algorithms for Weather Prediction at Exascale [PDF]

, 2019
In the simulation of complex multi-scale flows arising in weather and climate modelling, one of the biggest challenges is to satisfy strict service requirements in terms of time to solution and to satisfy budgetary constraints in terms of energy to ...
