时间Tue Oct 6 11:40:33 2009
Suppose the Linux scheduler chooses the process with the most credits for
run, and if no runnable processes can be chosen, the recrediting operation is
performed according to the following rule for every process in the system:
credits=credits/2+priority
For each timr slice, currently running process will lose one credit.
When the credits reach zero, it is suspended. According to the above
description, which of the following statements is correct?
(a)this credit system gives high priority to CPU-bound processes
(b)the scheduling will exhibit short response time
(c)interactive processes will receive fewer credits than non-I/O bound
processes
(d)nine of the above
答案有人写 D 也有人写 B 但我都不太了解题目意义
可以请高手指导一下吗?? 谢谢
