从用户模式增加线程数量 [英] Increase thread quantum from user-mode

问题描述

在Linux内核3.0+上是否可以从用户模式增加线程的数量?怎么样?

Is it possible on Linux kernel 3.0+ to increase thread's quantum from user-mode? How?

推荐答案

我怀疑是否有可能.我很快找到了此页面( http://www.javamex.com/tutorials/threads/thread_scheduling_2 .shtml )，这表明线程的量子长度始终是可变的，并受执行环境的许多属性的影响.

I doubt it's possible. I quickly found this page ( http://www.javamex.com/tutorials/threads/thread_scheduling_2.shtml ) which suggests that a thread's quanta length is variable anyway, and subject to many attributes of the execution environment.

我想，如果确实需要，可以编写一个改变它的内核模块，但是那样您就进入了痛苦的境地.

I suppose if you really needed to it should be possible to write a kernel module that alters it, but then you're entering painful territory.

您正在做什么，无论如何都需要更长的量子长度?也许还有另一种方法.

What are you doing that needs longer quanta lengths anyway? Maybe there's an alternative approach.
