问题描述

我正在研究Ubuntu项目.尚未找到sched_batch和sched_other之间的明显区别.谁能告诉我区别?

I am working on Ubuntu project. Have not found clear difference between sched_batch and sched_other. Can anyone tell me the difference?

推荐答案

使用sched_batch调度的线程被认为是非交互式的，但是受CPU限制并针对吞吐量进行了优化.因此，此策略对缓存更友好.默认的sched_batch时间片为1.5秒.此外，在使用SMP的情况下，sched_batch将迁移到具有高空闲(相对于非批处理线程)的内核.

Threads that are scheduled with sched_batch are assumed to be non-interactive, but CPU bound and optimized for throughput. Thus, this policy is more cache-friendly. The default sched_batch timeslice is 1.5 seconds. In addition, in case of SMP, sched_batch will migrate to a core with high idleness (with respect to non-batch threads).
