It is the only environmental model in existence today using a full, 3D curvilinear coordinate system, which results in increased accuracy, resolution, and reduced times to solution. UCOAM is a petascale model: resolving sub-km scale fluctuations requires large arrays (1010 elements); the curvilinear system requires large number of arrays (~100); communication occurs along all 3 axes; and full simulations generate TBytes of data. Consequently, this model requires parallelization. To facilitate our computations and data management, we have developed a Computational Environment (CE) based on the Cyberinfrastructure Web Application Framework (CyberWeb). In this poster we discuss our approach and challenges associated with parallelizing this new model and the design of the computational environment. We will also present results from scalability studies of this new parallel model. SUMMARY:Parallelization of the Unified Curvilinear Ocean Atmospheric Model PRIORITY:3 END:VEVENT END:VCALENDAR
