What is Scheduling

This chapter introduces a scheduling approach for cross-domain scientific workflow execution with timerelated QoS evaluation. Generally, scientific workflow execution often spans self-managing administrative domains to achieving global collaboration advantage. In practice, it is infeasible for a domain-specific application to disclose its process details for privacy or security reasons. Consequently, it is a challenging endeavor to coordinate scientific workflows and its distributed domain-specific applications from service invocation perspective. Therefore, in this chapter, the authors aim at proposing a collaborative scheduling approach, with time-related QoS evaluation, for navigating cross-domain collaboration. Under this collaborative scheduling approach, a private workflow fragment could maintain temporal consistency with a global scientific workflow in resource sharing and task enactments. Furthermore, an evaluation is presented to demonstrate the scheduling approach.
