MSF: A workflow service infrastructure for computational grid environments

초록

Globus has become a standard in the construction of Grid computing environments. However, it still needs more work and research to satisfy requirements from various grid applications such as workflow services. We propose a Meta Scheduling Framework (MSF) for workflow service management based on the Globus toolkit. The MSF provides an XML-based Job Control Markup Language (JCML) for describing information and procedures of applications including dependencies of jobs, a workflow management engine for scheduling complicated job flow, and an execution environment without the need for code modification or wrapping.
