  • Applying queueing theory to computing cluster energy optimization
    (2012) Sevalnev, Mark
     Master's thesis
    This work examines the current state of green IT and introduces a new software solution for saving energy in computing clusters. The work includes a comprehensive literature review on green IT by offering solutions to both computing clusters to improve energy efficiency and, more generally, other information technology solutions targeted to minimize energy consumption. It is known that the information technology systems resulted in 2% of all carbon dioxide emissions in 2007. Green IT focuses on developing of solutions to improve energy efficiency. Most solutions are based on the idea that the computing equipment is used only occasionally, but the device still consumes electricity while in the waiting mode. This necessitates the identification of such idle periods and to switch the device into a power saving mode. The work will go fundamentally through the necessary theoretical background: queuing theory, control theory, and statistical testing, so that a solution can be understood without knowledge of background literature. The solution for computing cluster energy minimization was also experimented with in practice.
