EKB: Semantic Information System for Energy-Aware Monitoring in Distributed Infrastructures
Hao Dong Zhu, Karel van der Veldt, Paola Grosso, Xiangke Liao, Cees de Laat · 2013
Most monitoring and discovery systems deployed in computer infrastructures do not take dynamic energy characteristics into consideration, and do not provide the mechanisms to exchange information across systems and administrative domains. Our energy-aware semantic information system, called Energy Knowledge Base (EKB), aggregates metadata and data from a large number of distributed information sources. The EKB supports therefore management, scheduling and management of computing and data transport tasks across domains. In computing infrastructures, the available information can differ quite a lot, changes frequently, has differing sources, but there is no well-defined data model. Our system leverages the Energy Description Language (EDL) to model dynamic energy-related attributes of resources from different layers, the EDL metadata provides data interoperability across providers. In this article we present the EKB architecture, show the usability.
