摘　　要：针对处理器的温度管理问题,在操作系统层次上提出一种轮转调度算法,改进基于门限温度的调度算法,并在Linux内核中实现了这两个算法.轮转调度算法有规律地让任务在双核上执行相等的时间,更好地平衡了处理器的温度,并且系统的吞吐量不受影响.To the issue of temperature management on microprocessor, a round robin scheduling algorithm as well as an improved threshold-based algorithm at OS level are proposed and implemented in Linux Kernel. Round robin algorithm regularly rotates tasks to each core for equal amount of time, therefore, it balances temperature between cores more effectively. Moreover, it has little impact on throughput.
