GJMF - a composable service-oriented grid job management framework

摘要

There exists a number of grid infrastructures in production use for a wide range of scientific applications. However, due to the complexities inherent to construction of distributed computing environments, many grid tools and applications remain tied to specific grids and grid middlewares. In this work we investigate best practices for grid software design and development, and propose a composable, loosely coupled Service-Oriented Architecture for grid job management. The architecture is designed for use in federated grid environments and defines a model for transparent grid access that aims to decouple grid applications from grid middlewares and facilitate concurrent use of multiple grid middlewares. The architecture model is discussed from the point of view of an ecosystem of grid infrastructure components, and is presented along with a proof-of-concept implementation of the architecture.
