Lazy Scheduling Based Disk Energy Optimization Method

发布时间：2022-12-09 01:51

　　Reducing the energy consumption of the storage systems disk read/write requests plays an important role in improving the overall energy efficiency of high-performance computing systems.We propose a method to reduce disk energy consumption by delaying the dispatch of disk requests to the end of a time window,which we call time window-based lazy scheduling.We prove that sorting requests within a single time window can reduce the disk energy consumption,and we discuss the relationship between the s...
