内容記述 |
The research of energy-efficient heterogeneous multiprocessor scheduling is becoming more and more popular today. The problem can be addressed as allocating tasks to the right core and set the appropriate operating frequency. In this paper, we present a task allocation algorithm for a single-ISA heterogeneous system consisted of two different types of cores: high-performance core and energy-efficient core. Based on the execution-variance of two types of cores, a heuristic that approximate the optimal load distribution is proposed. We experimentally simulate our method and compare it to state-of-the-art solutions, resulting average in about 20% less energy consumption (and up to 48% for some cases) with guaranteeing the deadline of all tasks. |
