Application Phase Behavior-Guided Thermal Management of Embedded Platforms

This letter presents a scheduling policy for multicore embedded applications based on their thermal phase behavior. The thermal phase-guided task allocation allows the scheduler to allocate tasks that run at elevated temperature to low-power cores while others running at normal temperature to high performing cores. The proposed phase-based thermal aware technique shows 15.4 °C reduction in average temperature and 30.5 °C in peak temperature when experimented with PARSEC benchmark applications targeted on the ODROID XU4 embedded platform.
