To reduce turnaround times of ESM simulations on future exascale HPC systems and to allow for novel ESM applications, future ESM codes need to enhance flexibility and portability. This will be especially important for the simulation of extreme events with very high spatial and temporal resolutions and possibly including chemical and aerosol weather.
Besides further theoretical development of the asynchronous scheduling concept and demonstrations based on ESM dwarfs from Topic 1, specific work in this topic focuses on developing on-line diagnostic tools to be run independently from the actual ESM code and which can later be used to alter the course of a simulation during its execution.
