Abstract (in Japanese) (See Japanese page) 
(in English) In data centers, the power consumption of air conditioners and that of fans in the server are affected by the heat distribution in the data center. Since server task distribution in data centers affects to the heat distribution, the total power consumption in data centers varies according to the task distribution even if the total amount of tasks remains unchanged. In this report, we evaluate the impact of task allocation on power consumption in data centers. We calculate the total power consumption in data centers based on the observation results obtained through real data center experiments. Through numerical evaluations using various data center models, we show that the power consumption in a tandem data center model is decreased by 26 % compared to that in a traditional data center model.
