An Energy-Efficient Task Scheduling Algorithm in DVFS-enabled Cloud Environment

A relative study of task scheduling algorithms in cloud computing environment

“…In this paper [9], a dynamic voltage and frequency scaling (DVFS) enabled Energy-efficient Workflow Task Scheduling algorithm (DEWTS) has been proposed, with the aim of acquire more power drop on top of assures the quality of service (QoS). The algorithm divides the parallel tasks in workflows to the suitable CPU, and use them at proper time to decrease power consumption and obtain demanded performance.…”

Energy Efficient Cloud Service Provisioning: Keeping Data Center Granularity in Perspective

“…To measure how far a system power model is from the ideal (energy proportional) one, Proportionality Gap(PG) [45] is defined as the normalized difference of the real power value and the ideal power value, which is indicated as P M ax × U , under a certain utilization level as shown in (4). Therefore, having proportionality gap values for a given device, we can reconstruct the power model of the device.…”

“…Hence, relying on the state-of-the-art hardware, we can meet the first element. Some work on energy efficient VM assignment [1][2][3][4][5][6] and migration [7] have been performed. Efforts have also been made to compare the private cloud and public cloud energy efficiency [8].…”

A Novel Energy Management System using Renewable Distribution Generation Units

“…Some of the literal shortcomings of DVFS include less scalability, state transition delay in turn diminishing results. [7,8] To maintain Quality of Service (QoS), DVFS based DEWTS (Energy efficient Workflow Task Scheduling Algorithm) was proposed as an improved version. The fact is that they could be actively used only for DVFS enabled devices and so the procedures make a long way to go.…”
