Abstract
A parallel implementation of the ensemble optimal interpolation (EnOI) data assimilation method for the high resolution general circulation ocean model is presented. The data assimilation algorithm is formulated as a service block of the Compact Modeling Framework (CMF 3.0) developed for providing the software environment for stand-alone and coupled models of the Global geophysical fluids. In CMF 3.0 the direct MPI approach is replaced by the PGAS communication paradigm implemented in the third-party Global Arrays (GA) toolkit, and multiple coupler functions are encapsulated in the set of simultaneously working parallel services. Performance tests for data assimilation system have been carried out on the Lomonosov supercomputer.
