Abstract (in Japanese) (See Japanese page) 
(in English) In this report, we propose a server task assignment method for leveling the temperature distribution of data center servers to reduce air conditioning power consumption. Our method is based on the simulation of data center's airflow to find a server with the highest temperature and that with the lowest temperature and moves the server's task from the former server to the latter server. Evaluation results show that we can decrease the power consumption of air conditioners by 9.6% and 45.6% for the traditional data center model and the novel data center model developed by our research group, respectively. Furthermore, by considering the effect of waste heat utilization, the total power consumption in our novel data center model can be decreased by up to 22.4%.
