The energy efficient approach to assigning tasks in a server cluster

Abstract

The approach to increasing energy efficiency of the data center computing by using energy efficient tasks scheduling within the server cluster as an integral part of the data center infrastructure has been described in the paper. The proposed approach is characterized by taking into account both energy efficiency and performance parameters. The approach is implemented in the task scheduling algorithm. The main idea of the algorithm is to carry out the preliminary attestation of each cluster nodes individually. The efficiency of the proposed approach has been tested by the simulation process and proved experimentally. The approach has shown a gain of up to 49,09% by the performance criteria and up to 9,04% by the energy efficiency criteria for big heterogeneous clusters.
