Abstract: We have tested how queueing theory can be applied to improve energy efficiency of scientific computing clusters. Our method calculates the number of required servers based on the arrival rate of computing jobs and turns on and off computing nodes based on this estimate. Our tests indicated that this method decreases energy consumption. However simultaneously the average lead time tends to increase because of higher waiting times in cases when the arrival intensity goes up.
