Data Distribution Management Modeling and Implementation on Computational Grid

摘要

This paper presents a design and development of a data distribution management modeling in computational grid. The modeling focuses on system performance improvement of a satellite cluster management system which uses an inter-federation communication in HLA (High Level Architecture)-compliant grid system. The inter-federation communication allows to execute a complex large-scale cluster management system with distributed satellites and share the dispersed data assets among satellite components collaboratively. In addition, this paper discusses the data distribution management modeling with centralized and decentralized approaches to improve system performance and scalability of satellite cluster management. The analytical and empirical results on the heterogeneous OS-based computational grid show usefulness of data distribution management and inter-federation communication in the satellite cluster management system.
