3E: Energy-efficient elastic scheduling for independent tasks in heterogeneous computing systems

► An energy-efficient elastic scheduling strategy 3E was proposed. ► 3E is designed for independent task scheduling in heterogeneous computing systems. ► 3E can adjust supply voltage according to system workload. ► 3E makes the best trade-offs between energy consumption and user expected finish times. ► 3E improves the scheduling quality and enhances the system elasticity.
