异构多核调度算法研究综述

A Survey of Heterogeneous Multi-core Scheduling Algorithms

随着嵌入式系统的发展,异构多核由于运算能力强、成本低等特点,已成为当前关注热点。合适的任务调度算法才能发挥异构多核处理器的全部性能,目前运行在异构多核处理器上的操作系统大多采用同构多核处理器的任务调度算法,并不能适用于所有异构多核处理器,研究异构多核性能的任务调度算法意义重大。阐述几种异构任务调度算法,对比它们在任务调度上的优缺点,指出现阶段遇到的问题并展望其未来研究趋势。

With the development of embedded systems,heterogeneous multi-core has recently become the mainstream of research due to its strong computing power and low cost.However,the architecture of heterogeneous multi-core processors is complex,and the operating system working on it for task scheduling has become a difficult and important point of research.The algorithms originally working on homogeneous multi-core processors did not perform well on heterogeneous multi-core processors.In order to give full play to the performance of heterogeneous multi-core processors,a good task scheduling algorithm is necessary.This article describes several multicore heterogeneous task scheduling algorithms,and compares the advantages and disadvantages of these algorithms in task scheduling,points out the problems encountered in the emergence stage and looks forward to its future research trends.
