Abstract

A task migration method is proposed for energy savings in multiprocessor real-time systems. The method is based on the portioned scheduling technique which classifies each task into a fixed task or a migratable task. The energy-aware migration with specified parameters is formulated as a linear programming problem, and optimal solution is given. Furthermore, the method is extended to more general case with a complete migration algorithm. Simulation results showed significant energy savings over existing methods.
