Feasibility Study: Weather Forecasts with ICON and IFS

Performance of IFS and ICON in global NWP simulations

The graph shows the number of forecast days per compute day that can be achieved by global ICON and IFS models (no I/O).


Parallel Performance of ICON


The graph shows the parallel performance of the ICON software using ECHAM physics on a 5km-resolution aqua-planet experiment. Good strong scalability is observed on the partition compute2 hosted at DKRZ. Find out more about ICON scalability and benchmarking here (restricted access).
