Keywords: middleware for integration; scientific workflow deployment; grid-based systems.

Abstract:
Scientific workflows are generally programmed and configured to be executed by a specific grid-based system. The integration of heterogeneous grid computing platforms in order to build more powerful infrastructures and the flexible deployment and execution of workflows over them are still two open challenges. Solutions based on meta-scheduling have been proposed, but more flexible and decentralized alternatives should be considered. In this paper, an alternative framework based on the use of a tuple-based coordination system and a set of mediation components is proposed. As a use case, the First Provenance Challenge has been implemented using two different workflow technologies executed over the framework, Nets-within-Nets and Taverna, and transparently deployed on two different computing insfrastructures. The proposed framework provides users with scalability and extensibility mechanisms, as well as a complete deployment and scheduling environment suitable for a wide variety of scenarios in the scientific computing area.
