Cooperative Negotiation And Scheduling Of Scientific Workflows In The Collaborative Climate Community Data And Processing Grid

摘要

As part of the D-Grid initiative the C3Grid project provides a service oriented Grid infrastructure to support workflow-based scientific applications for Earth System Science. In this paper, we review conceptual as well as technical details of the architecture and implementation concerning this infrastructure and focus especially on the Grid middleware layer that deals with workflow scheduling and data management. Besides the design of these loosely coupled services, their collaboration is a further point of interest in this work. We propose a mode of cooperative interaction and show the realization details in the C3Grid architecture.
