Dynamic Adaptive Power Management For — And By — A Java Virtual Machine

Traditionally, adaptive power management has been performed at the operating system (OS) level. We present a dynamic adaptive power-management plugin for the Java Virtual Machine (JVM) that improves the precision of power management decisions by utilizing fine-grained high-level program state information available to the virtual machine, but often invisible to the OS. In contrast to power management components situated at the OS level, our virtual machine plugin injects runtime profiling probes and power management triggers at the Java bytecode-level and is thereby independent of target architecture, JVM implementation, and host operating system.
