Abstract

Service Level Agreements (SLAs) are currently one of the major research topics in Grid Computing resulting in a language definition for specification of SLAs and corresponding system architectures. However, previous work solely addresses problems for monolithic Grid jobs. The description of a workflow (job flow) considers characteristics of correlated sub-jobs, thus the problem grows more complex in terms of management, SLA specification, fault reaction etc. Therefore, this paper presents a system architecture to ensure SLAs for Grid-based workflows and a corresponding language for the SLA specification.
