SUMMARY:MS3C - ICON-Next: Current Developments in Rewriting the ICOsahedra
 l Non-hydrostatic (ICON) Model for Emerging Architectures
DESCRIPTION:Minisymposium\n\nThe next step in climate modeling is so-calle
 d "storm-resolving" earth system models (SR-ESMs), which work at kilometer
 -scale. SR-ESMs make it possible for the first time to directly simulate s
 mall-scale processes like the formation of thunderstorms. Emerging exascal
 e high-performance computers have the necessary computing power to carry o
 ut such high-resolution simulations for longer simulation times. These mai
 nly heterogeneous hardware architectures pose challenges for all scientifi
 c software development efforts, and the ICON weather and climate model is 
 no exception. Several initiatives address these technical challenges in or
 der to exploit the possibilities of km-scale ICON simulations, for example
  to improve forecast skills or to produce climate information of the highe
 st possible quality. This minisymposium will present the research directio
 n of four of these initiatives: ICON-22, WarmWorld, EXCLAIM, and ICON-C. W
 hile the first three are independent projects, they are all tied together 
 through the common ICON model and the need to enable scalable development 
 while ensuring performance portability. These three projects will also con
 tribute to the fourth: the ICON-Consolidated effort will pull together var
 ious developments into a consolidated ICON software package. At PASC22, fi
 rst results of each project will be presented along with their synergies t
 owards the overarching goal of storm-resolving simulations.\n\nExtreme Sca
