Approach to Business-Policy based Job-Scheduling in HPC

摘要

Job-Scheduling behavior of a High Performance Computing (HPC) provider is typically defined in the way that implicitly corresponds to its business policies. Represented mainly by a set of business rules or objectives, business policies form means to guide and control the business of HPC service provisioning. Because in HPC domain business policies exist mostly implicitly, administrators configure schedulers intuitively and subjectively. This makes it hard for business people to assess whether the actual scheduling behavior corresponds to current business policies, as there is no link defined between job-scheduling and business policies. The question, whether the scheduling behavior is configured correctly, cannot be answered without providing relationships between business-policies and job-scheduling strategies. Hence, more general question is: how much influence does business policy actually have on job scheduling? In this paper, we present an approach allowing' investigating how business-policies relate to the job-scheduling in HPC domain.
