How to run tasks with priority?

Hello everyone,


I want to run tasks with priority, i.e. among several simultaneous running
tasks, the task with the higher priority will have more chances to occupy
CPU time. I have the following 2 issues dealing with the implementation of
such feature.

- To define each task as a thread or as a method? How to change the
priority of each task dynamically when they are running?

- The priority feature of Java thread does not meet my requirement, since I
can not define priority precisely. For example, I want to define that a
task with priority A will occupy CPU time 3 times than a task with priority
B.

I am wondering whether I can find similar open source projects or tutorials?


Thanks in advance,
George
