Disk layout optimization for reducing energy consumption
Excessive power consumption is becoming a major barrier to extracting the maximum performance from high-performance parallel systems. Therefore, techniques oriented towards reducing power consumption of such systems are expected to become increasingly important in the future. Since disk systems of high-performance architectures are known to constitute a large fraction of the overall power budget, they form an important optimization target. Previous work on disk power management focuses primarily on hardware based schemes. However, since disk access pattern, i.e., the order in which disks on a system are accessed, is mainly shaped by the program code access pattern and disk layout of data, software techniques can also play a critical role in disk power management. Motivated by this observation, this paper proposes and evaluates a profile-driven disk layout optimization scheme for reducing energy consumption. The proposed scheme analyzes the array access traces obtained through profil...
