Many computing systems have adopted the Dynamic Voltage Scaling (DVS) technique to reduce energy consumption by slowing down operation speed. However, the longer a job executes the more energy in leakage current the processor consumes for the job. To reduce the power/energy consumption from the leakage current, a processor can enter the dormant mode. Existing research results for leakage-aware DVS scheduling perform procrastination of real-time jobs greedily so that the idle time can be aggregated as long as possible to turn off the processor.
