SUMMARY:Performance Portability Options for Earth Systems Models on Emergi
 ng Computer Architectures
DESCRIPTION:Minisymposium\n\nPerformance Portability Options for Earth Sys
 tems Models on Emerging Computer Architectures\n\nMcIntosh-Smith\n\nAs we 
 invest considerable effort in getting the community of Earth Systems Model
 ling codes ready for Exascale, we must choose which programming models and
  frameworks we adopt carefully. With a diverse range of different CPUs and
  GPUs from a wide range of vendors, it is crucial that this investment ena
 bles performance portability. In this talk we will look at the results fro
 m recent evaluations of potential candidates for performance portability s
 olutions, such as SYCL, a core part of Intel's oneAPI initiative, and Open
 MP target offload. We will compare these approaches to domains specific la
 nguages, and explore where each might be the optimal choice.\n\nDomain: CS
  and Math, Climate and Weather, Physics
