Abstract:
Service provisioning in High Performance Computing (HPC) is typically defined in the way that implicitly corresponds to business policies of the HPC provider. Business policies, represented by business rules, objectives or directives, form means to guide and control the business of HPC service provisioning, affecting interdependently resource-management, SLA-management, contracting, security, accounting, and other domains. As business policies in HPC domain exist mostly implicitly, administrators configure resource management systems mostly intuitively and subjectively. This makes it hard for business people to assess whether business polices are consistent, and resource management behavior corresponds to business policies (and vice versa), as no linkage between business policies and scheduling policies is defined yet. In this paper we analyze relationships between business policies and resource management behavior, (1) presenting approach allowing to investigate how business policies and scheduling policies relate together, (2) identifying sources and key-factors influencing scheduling behavior, (3) describing relationships between those key-factors, and (4) using Semantics of Business Vocabulary and Business Rules (SBVR) for definition of business policies and transformation rules, capable to translate business policies into scheduling policies.
