| Abstract: | A predictive shutdown method based on active period was proposed.This method utilized the relationship between active period and idle period,and also imported the dynamic adaptive factor.Not only does it improve the prediction accuracy of idle periods which change greatly,but also adjusts and adapts to the change in workload quickly.Experiments show that this method achieves better performance and energy saving than traditional ones. |
