To realize its potential, a U.S. Earth system modeling and prediction capability must encompass a network of agencies and organizations that contribute model components, infrastructure, and scientific and technical expertise. The model component contributions must be integrated using coupling software, the coupled systems optimized for emerging computing platforms, and the predictive skill of the resulting models assessed using standard metrics. We propose to provide these integrative functions for the Earth System Prediction Capability ESPC, using as a reference application a version of the Community Earth System Model CESM running an optimized version of the HYbrid Coordinate Ocean Model HYCOM. The objectives of our work are To establish an ESPC Coupling Testbed that allows for collaborative research into coupling technologies, and use it to prototype multi-model optimization techniques focused on computing systems with accelerator technologies. To support migration of optimization strategies from the ESPC Coupling Testbed to infrastructure packages and coupled model applications, and provide support for coupling of optimized components in the ESPC program. To update a newly coupled CESM-HYCOM model configuration with an optimized version of HYCOM and assess the coupled system performance. To evaluate the CESM-HYCOM model using standard measures of predictive skill, and promote the usage of standard metrics by other models in the program. To extend ESPC-related computational committees to address new requirements driven by changes in computing architectures and program needs, and to initiate scientific committees.
