Information on modifying your process priority using nice.

How to nice your processes

It is important to nice intensive processes so that they don’t interfere with using the most basic functions of the research server such as changing directories or moving files.

The nice and renice commands adjust the priority of a process. ARC recommends that all users nice all of their processes with a value of at least 5. To nice a process when it is started type:

$ nice +5 [other_commands]

where [other_commands] is the command you actually wan to run. If you have already started a job and want to nice it after the fact, you can use the renice command to do this. First identify the process ID that you wish to nice:

$ ps -u

Then run renice on it:

$ renice +5 [PID]

where [PID] is the process ID.
