Application-Oriented Designs -- Building Applications from a Web Service based Component Architecture -- Components for High-Performance Grid Programming in Grid.IT -- Towards Building a Generic Grid Services Platform: A Component-Oriented Approach -- A Solution for Adapting Legacy Code as Web Services -- Middleware Architecture -- A Graphical Modeling Environment for the Generation of Workflows for the Globus Toolkit -- On Hierarchical, Parallel, and Distributed Components for Grid Programming -- ICENI: An Integrated Grid Middleware to Support E-Science -- An Architecture for a Portable Grid-Enabled Engine -- Communication Frameworks -- Dynamic Adaptation of Parallel Codes: Toward Self-Adaptable Components for the Grid -- HOCS:Higher-Order Components for Grids -- The Component Architecture of Open MPI: Enabling Third-Party Collective Algorithms*.Component Models and Systems for Grid Applications is the essential reference for the most current research on Grid technologies. This first volume of the CoreGRID series addresses such vital issues as the architecture of the Grid, the way software will influence the development of the Grid, and the practical applications of Grid technologies for individuals and businesses alike. Part I of the book, Application-Oriented Designs, focuses on development methodology and how it may contribute to a more component-based use of the Grid. Middleware Architecture, the second part, examines portable Grid engines, hierarchical infrastructures, interoperability, as well as workflow modeling environments. The final part of the book, Communication Frameworks, looks at dynamic self-adaptation, collective operations, and higher-order components. With Component Models and Systems for Grid Applications, editors Vladimir Getov and Thilo Kielmann offer the computing professional and the computing researcher the most informative, up-to-date, and forward-looking thoughts on the fast-growing field of Grid studies.
