Component-based system for grid application workflow composition

Abstract

An application working within a Grid environment can be very complex, with distributed modules and decentralized computation. It is not a simple task to dispatch that kind of application, especially when the environment is changing. This paper presents the design and the implementation of the Application Flow Composer system which supports building the description of the Grid application flow by combining its elements from a loose set of components distributed in the Grid. The system is based on the Common Component Architecture (CCA) and uses the CCA distributed component description model. OGSA Registry Grid Service is applied for storing component description documents. The performance tests confirm the feasibility of this approach. © Springer-Verlag Berlin Heidelberg 2003.
