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-optimal migration with specified parameters is formulated as a linear programming problem, and a simple solution is given. Then, the method is extended to more general case with a complete migration algorithm. Its effectiveness is evaluated through simulation studies. Simulation results on two commercial processor models show that the method achieves significant energy savings over existing methods in case of medial and low system utilization. |
