Engineering Computational Service Grid: A Flexible Engineering Computational Environment Based on Grid Computing

An ideal engineering computational environment for solving design problems should be flexible, which is characterized by helping designers to establish solution strategy conveniently and integrating design resources effectively. In this paper, a flexible engineering computational system called engineering computational service grid (ECSG) based on grid portal technology and workflow technology is presented, and the architecture of ECSG is described detailedly. For managing solution strategy of engineering computational job, the structure of BPEL (business process execution language) based workflow management subsystem is put forward, and an application scenario of ECSG is given. The research results aforementioned can clarify the functional system of engineering computational environment and provide an approach to constructing flexible engineering computational environment.
