SUMMARY:EarthWorks: Towards an Earth System Model at Storm Resolving Resol
 utions
DESCRIPTION:Minisymposium\n\nEarthWorks: Towards an Earth System Model at 
 Storm Resolving Resolutions\n\nLoft\n\nThe National Center for Atmospheric
  Research (NCAR), along with Colorado State University, have teamed up in 
 an NSF-funded project called EarthWorks to develop a (mostly) GPU-resident
  Earth System model capable of running at global storm-resolving (GSR) res
 olutions. Numerous studies have shown that GSR models are able to realisti
 cally simulate important Earth system processes that lower-resolution mode
 ls miss. EarthWorks builds on the successful deployment of a GPU-enab
 led version of the Model for Prediction Across Scales - Atmosphere (MPAS-A
 ) within the IBM-GRAF forecasting system, now running daily at The Weather
  Company/IBM. EarthWorks leverages: 1) Community Earth System Model (CESM)
  models and infrastructure; 2) scalability improvements made to the Commun
 ity Atmosphere Model (CAM) within CESM through an NCAR initiative called t
 he System for Integrated Modeling of the Atmosphere (SIMA); and 3) MPAS-Oc
 ean model developed and maintained at Los Alamos National Laboratory as pa
 rt of the Climate, Ocean and Sea Ice Modeling (COSIM) project. A
 ll components of EarthWorks are envisioned to run on the same quasi-unifor
 m Voroni mesh, with a shallow, tropospheric (60-level) and deep, stratosph
 eric (90 level) vertical resolution. The performance objective of EarthWor
 ks will be to demonstrate 0.5 years-day at 3.75 km by 2025. This talk
  will detail the ongoing porting, tuning and optimization work that has be
 en performed in preparation for running MPAS-CAM and MPAS-O at storm-resol
 ving resolutions as part of EarthWorks. As our previous work on MPAS-A, th
 is project will use a directive-based approach based on OpenACC.\n\nDomain
