SUMMARY:EarthWorks: Scaling a Fully Coupled Climate Model to Run at Ultra-
 High Resolutions
DESCRIPTION:Minisymposium\n\nSheri Voelz (National Center of Atmospheric R
 esearch)\n\nEarthWorks is a US NSF-funded project that is led through Colo
 rado State University with a partnership through NCAR which aims to run a 
 fully coupled Earth system model at 3.75 km resolution, global storm-resol
 ving resolutions. The EarthWorks’ model configuration leverages the infras
 tructure of the Community Earth System Model (CESM) to couple the CAM-MPAS
  model with the MPAS Ocean, MPAS Sea Ice, and the Community Land Model (CL
 M) models.\nOur fully coupled model configuration has been successfully te
 sted in multi-year simulations down to the 15 km resolution on CPU’s, with
  shorter functional tests being completed at our target resolution of 3.75
  km. In order to achieve our performance targets, we need to create a GPU 
 resident version of our model. This presentation will focus on the refacto
 ring work that is well underway and the acceleration that has been obtaine
 d thus far. We will also discuss the software engineering challenges that 
 this project has faced and how they have been overcome.\n\nDomain: Climate
 , Weather, and Earth Sciences\n\nSession Chairs: Claudia Frauen (DKRZ) and
  Balthasar Reuter (ECMWF)
