A collaborative task planning and development environment on the Cloud/Grid

Abstract

A Grid system is a promising solution for sharing distributed resources of registered participants to perform tasks whose demands may exceed the capacity of individual participating organization. However, the collaborative aspect of Grids is still underdeveloped as they lack features and mechanisms for human interaction and collaboration. This paper presents a prototype system for collaborative task planning and workflow development over a Grid implemented as a Rich Internet Application. It allows the participants to design their joint workflow interactively and collaboratively in a high level graphical notation. The resulting workflow can be automatically translated into Business Process Execution Language (BPEL) for testing and execution with a few clicks and forms the basis for further refinement and collaboration. This collaborative workflow design application is part of our larger Active Assistive Cloud/Grid infrastructure.
