Distributing data in composite grid applications for grid computing

Summary form only given. Automatic data distribution for composite grid applications requires that meshes be mapped to a parallel machine in a manner that balances the load while minimizing communication. To provide beginning support for mapping to computational grids, the automatic data distribution toolkit (ADDT) supports heterogeneous environments with varying communication and computational capabilities. This paper describes the applications supported by ADDT, the mapping techniques used, the Web interface for the toolkit, as well as planned future developments.
