Abstract

A grid workflow is regarded as a fundamental service in a grid environment. To design a user friendly end-to-end grid workflow model is generally a challenging task for general users. In this paper, we propose the concept of grid workflow component, which can be created and then reused to construct the grid workflow model dynamically. This paper firstly presents a framework for dynamic grid workflow. Then the grid workflow component model, which consists of a semantic sub-model and a syntactic sub-model, is defined. Next the methodologies for reusing grid workflow component, especially its search strategy and assembling patterns, are discussed in the paper.
