Resource Management
Many of you are leaving processes running unintentionally.
To see what is running, login to a machine (ada3.eecs.utk.edu)
and type:
ps -fu username
To kill a process, type: kill -9 PID where PID was shown when you
typed the ps command.
To check the resource usage on a machine, just type: top
To exit "top", hit control-C.
When there are many users and you want to be nice to them, you can
set the resource usage level of your process by typing:
nice +5 command &
The number between "nice" and "command" can be up to 19 (which is being
VERY nice).
Example command: icfb &
