CPU Utilization on IBM x3755

[Won De Erick]

thanks for the lights.

I may not be well verse in interpreting the output, but I am using top -S to make other system processes (like pager, swapper) visible.
I just wondered why the command name should be idle : cpu0, etc. instead of giving a little bit more descriptive name (like what you said, kernel thread bla bla). With this, it would be more understandable. An ordinary user like me could mistakenly interpret it as an "actual" process. 

Well thanks Jeremy!

They're not really "processes", just kernel threads or kernel-level
processes (for lack of better term).

The utilities you're using are correct (ps and top), but I don't know
why you're using top -S since it's pretty apparent you don't know how to
read the output.  :-)

You shouldn't be using -S if you're just interested in actual processes
on the UNIX machine itself.
