An Expert Green Scheduling System for Saving Energy Consumption

Abstract

The rising energy consumption of large-scale distributed computing systems raises operational expenses and has a negative impact on the environment (e.g. carbon dioxide emissions). The most expensive operating cost aspect in data centers (DC) is the electricity consumption for cooling purposes (DC). Inefficient cooling causes excessive temperatures, which leads to hardware breakdown. To solve this issue, novel thermal-aware green scheduling algorithms were developed to dramatically reduce cooling energy consumption costs while avoiding high thermal stress conditions such as big hotspots and thermal violations while preserving typical competitive performance. As a result of this research, the expert green scheduling algorithms can save cooling electricity usage during job execution when compared to nongreen scheduling methods. Thus, the expert green scheduling algorithms clearly outperform nongreen scheduling algorithms in terms of cooling power usage effectiveness. In addition, the proposed algorithms enhance overall data center reliability by intelligently balancing workloads based on predicted thermal profiles, thus reducing the frequency of hardware failures and prolonging the operational life of computing resources. Experimental evaluation using real-world benchmark traces further demonstrates that the algorithms not only save energy but also maintain service-level agreements (SLAs) and throughput in large-scale grid environments.
