Prototyping of the ESMF Using DOE's CCA

Typical earth system models involve coupled model components in high performance computing (HPC) environments. There are two emerging component-based frameworks for developing HPC applications. The Earth System Modeling Framework (ESMF), funded by NASA Earth System Technology Office (ESTO) Computational Technologies (CT) Project, defines a domain specific component interface for earth system models. Common Component Architecture (CCA), funded by DOE, defines a general component model for HPC environments. The purpose of this prototyping work is to investigate how CCA can support the earth system models that are ESMF compliant. In particular we will present our findings on the process of integrating a simple coupled climate model into the CCA’s CCaffeine framework.
