Hierarchical power management with application to scheduling

This paper presented a hierarchical power management architecture which aims to facilitate power-awareness in an Energy-Managed Computer (EMC) system with multiple components. The proposed architecture divides PM function into two layers: system-level and component-level. The system-level hierarchical PM was formulated as a concurrent service request flow regulation and application scheduling problem. Experimental results showed that a 25% reduction in the total system energy can be achieved compared to the optimal component-level DPM policy. Categories and Subject Descriptors C.4 [Computer System Organization]: Performance of Systems. General Terms Algorithms, Performance, Design, Experimentation. Keywords Hierarchical power management, application scheduling, CTMDP.
