Abstract
A fundamental challenge in development of predictive models of complex environmental and biological systems is posed by the extreme disparity between the physical scales (length and time) at which fundamental molecular understanding is obtained and those at which model predictions are required. This project is aimed at the development of an integrated multiscale modeling framework that accounts for top-down controls of environmental processes on biological responses at small scales, and for feedbacks of small small-scale biological processes on ecosystem-scale function. This project will take the initial steps toward development of such a framework through evaluation and preliminary application of available multiscale coupling frameworks to the conceptual system of interest to be defined by the System Thrust focus project. This project will identify and evaluate a number of available multiscale modeling approaches (with modification or development as needed) and then select one or more approaches that are best suited to EMSL science problems. This will be based on a detailed literature survey of available multiscale and multiphysics model coupling software frameworks. We will limit the survey to those frameworks that can be applied within a high-performance (parallel) computing environment like the Cascade system. Based on the results of the literature survey and the preliminary outcomes of the System Thrust focus project, we will identify one or more frameworks to be implemented on Cascade. We will work with the System Thrust focus project to identify specific system components to serve as test case studies, and we will implement the candidate framework(s) for those component linkages. Finally, we will use the evaluation and case study results to define a path forward for future research and development to fully develop a comprehensive multiscale computational and experimental framework to integrate the results of other SSA thrust areas and for application to EMSL user projects.
