标 题: One OS scheduling question
发信站: BBS 未名空间站 (Wed Feb 13 22:06:32 2008)
This is an interview question.
To give the fast response in the realtime system, we give some process/
thread high priority to run. As a result some lower process/thread may be
starved. How could we solve it? Is there any other solution besides rising
the priority? |
