Java CoG Kit Workflow Concepts for Scientific Experiments
Gregor von Laszewski · 2005
Many scientific simulations and experiments require the coordination of numerous tasks posed by interdisciplinary research teams. Grids can provide access to the necessary high-end resources to conduct such tasks. The complex tasks and their interactions must be supported through convenient tools. To address this issue, we introduce a number of Grid abstractions that make the development of Grid middleware-independent tools possible and allow for the integration of a number of commodity tools. Our vision is implemented through an integrated approach based on a layered architecture that bridges the gap between Grid middleware and scientific applications. Our abstractions include specialized services, a Grid workflow engine and language, and Grid faces -- graphical abstractions that can be employed in science portals and standalone applications.
