Title:

MPH: A Library for Coupling Multi-Component Models on Distributed Memory Architectures and its Application

Abstract:

A growing trend in developing large and complex applications on today's Teraflop computers is to integrate stand-alone and/or semi-independent program components into a comprehensive simulation package. One example is the climate system model, which consists of atmosphere, ocean, land-surface and sea-ice. Each component is semi-independent and has been developed at different institutions. We study how this multi-component multi-executable application can run effectively on distributed memory architectures. For the first time, we clearly identify five effective execution modes and develop the MPH library to support application developments utilizing these modes. MPH performs component-name registration, resource allocation and initial component handshaking in a flexible way. MPH has been adopted in Community Climate System Model (CCSM) and some other models. Current CCSM model is a single-component, multi-executable system. In this talk, we will also present a status of single-executable CCSM development with MPH mechanism.
