Energy-aware Scheduling in Virtualized Datacenters
"... Abstract—The reduction of energy consumption in large-scale datacenters is being accomplished through an extensive use of vir-tualization, which enables the consolidation of multiple workloads in a smaller number of machines. Nevertheless, virtualization also incurs some additional overheads (e.g. v ..."

.g. virtual machine creation and migration) that can influence what is the best consolidated configuration, and thus, they must be taken into account. In this paper, we present a dynamic job scheduling policy for power-aware resource allocation in a virtualized datacenter. Our policy tries to consolidate
Preemption-aware Energy Management in Virtualized DataCenters
"... Abstract—Energy efficiency is one of the main challenges that datacenters are facing nowadays. A considerable portion of the consumed energy in these environments is wasted because of idling resources. To avoid wastage, offering services with variety of SLAs (with different prices and priorities) is ..."

based on user performance requirements. We have implemented our proposed energy management policy in Haizea as a real scheduling platform for virtualized datacenters. Experimental results reveal 18 % energy conservation (up to 4000 kWh in 30 days) comparing with other baseline policies without any major
Energy-Aware Capacity Scaling in Virtualized Environments with Performance Guarantees ∗
"... We investigate the trade-off between performance and power consumption in servers hosting virtual machines running IT services. The performance behavior of such servers is modeled through Generalized Processor Sharing (GPS) queues enhanced with a green speed-scaling mechanism that controls the proce ..."

Energy-Aware Application-Centric VM Allocation for HPC Workloads
"... Abstract—Virtualized datacenters and clouds are being increasingly considered for traditional High-Performance Computing (HPC) workloads that have typically targeted Grids and conventional HPC platforms. However, maximizing energy efficiency, cost-effectiveness, and utilization of datacenter resourc ..."

resources while ensuring performance and other Quality of Service (QoS) guarantees for HPC applications requires careful consideration of important and extremely challenging tradeoffs. An innovative application-centric energy-aware strategy for Virtual Machine (VM) allocation is presented. The proposed
Thermal-aware task scheduling to minimize energy usage of blade server based datacenters
- in IEEE International Symposium on Dependable, Autonomic and Secure Computing (DASC’06
, 2006
"... Blade severs are being increasingly deployed in modern datacenters due to their high performance/cost ratio and compact size. In this study, we document our work on blade server based datacenter thermal management. Our goal is to minimize the total energy costs (usage) of datacenter operation while ..."

Evaluating the Need for Complexity in Energy-aware Management for Cloud Platforms
"... In order to curtail the continuous increase in power con-sumption of modern datacenters, researchers are respond-ing with sophisticated energy-aware workload management methods. This increases the complexity and cost of the management operation, and may lead to increases in failure rates. The goal o ..."

Towards Proactive Resource Management in Virtualized Datacenters
"... Proactive resource management involves taking actions to make resources available for upcoming load spikes. Proactive resource management is highly desirable for managing resources in a multi-tenant cloud where it is common to have hot-spots at some loca-tions, while still having spare resources sca ..."
