Increase thread quantum from user-mode

Question

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

Answer 1

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.

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.

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