Efficient Communication Between Parallel Programs with InterComm

We present the design and implementation of InterComm, a framework to couple parallel components that enables efficient communication in the presence of complex data distributions within a coupled application. Multiple parallel libraries and languages may be used in different modules of a single application. The ability to couple such modules is required in many emerging application areas, such as complex simulations that model physical phenomena at multiple scales and resolutions, and remote sensing image data analysis applications. The complexit
