Hi,

You can use the 'nice' utility (man nice). To change
the priority of a process programatically, you can use
the nice() function (man 2 nice).

   You can also use renice, to change the process priority of an already 
running process.  Unfortunatelly, you can only lower the priority of the 
process.  With renice, You need to be root to put higher the priority of 
a running process.  Still, it is usefull if you want to lower the 
priority of a group of process that take lots of ressources on a system 
(ex. lowering the priority of a big "find" request all over your hardisk 
while you are doing something else more important).

   As far as I know, both nice and renice are available for every modern 
Unix systems.

PROCESS PRIORITY

[Saurabh Jain]

I am new to Linux kernel and I have got confused . Please can anyone give
answer to my questions :

Q1 -> Is static priority of a thread changes or not ? If changes then how
it changes ?

Q2 -> What is the default value of static priority and dynamic priority for
a process     and thread in Linux kernel ?

Q3 -> What is the initial value of static priority and dynamic priority for
a newly created thread and process?

Q4 -> When we talk about the priority of a process or thread (incrementing
/ decrementing priority , setting priority etc. ) , then which priority we
are referring , is it static priority or dynamic priority ?

  careful ... while a very good book, it *is* starting to show its age
just a bit. there are no really current kernel books out there.
