How to determine the cpu number on which the process is running
 
Hi, guys:

When I fork multiple processes, is there some command or c function to see the cpu number on which the processes are running?


Thanks

You can see it in top -

Code:
top
f
j
.. the 'P' column will now be visible which is the processor that the task was last run on.

Please note that the task scheduler in the 2.6 series kernel will *automatically* redistribute processes in a SMP system if the cpu's are not equally loaded

cheers

Thanks. Which argument of "top" command I need to use? Because I did not see the 'P' column.
