Joint flow routing-scheduling for energy efficient software defined data center networks
TL;DR: This paper developed a component for energy monitoring and routing in OpenNaaS and shows that the combination of priority-based shortest routing and exclusive flow scheduling achieves about 5%-35% higher energy efficiency without performance degradation.
Energy-aware semantic modeling in large scale infrastructures
TL;DR: An basic knowledge system called Energy Knowledge Base (EKB) is prototyped that provides contextbased information retrieval support for applications, in order to make energy aware decisions on scheduling and resource allocation.
Journal ArticleDOI
A semantic enhanced Power Budget Calculator for distributed computing using IEEE 802.3az
Zhu Hao,Karel van der Veldt,Zhiming Zhao,Paola Grosso,Dimitar Pavlov,Joris Soeurt,Xiangke Liao,Cees de Laat +7 more
TL;DR: An energy budget calculator that includes the energy model of 802.3az compliant Ethernet devices and supports the resource management service is devised and a solution for enhancing the calculator by using a semantic energy information system is presented.
Proceedings ArticleDOI
EKB: Semantic Information System for Energy-Aware Monitoring in Distributed Infrastructures
TL;DR: The EKB 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 and the usability is presented.
Journal ArticleDOI
Evaluation of non-linear power estimation models in a computing cluster
TL;DR: It is proved that models trained using the system-level full features have the highest accuracy comparing to only use part of features, and it is proven that a multiple-variable linear regression approach is more precise than a CPU-only linear approach.
