Research on componentized design and parallelization towards POP ocean model using ESMF

In order to address the problem that it is difficult to port and utilize existing abundant reusable modules during the development of a new model due to the tight coupling among different modules in a contemporary ocean model, the authors decomposed the parallel ocean model of parallel ocean program (POP) into a set of scientific procedures, and then encapsulated the implementation codes into reusable components with the Earth System Modeling Framework (ESMF). In addition, the ESMF parallelism was applied to the new component-based POP, which can help to further enhance the efficiency. The experiment results showed that the proposed approach, on the premise of correctness, improved the reusability and maintainability of the model significantly, as well as its performance.
