ps command displays multiple processes

Hi,

I have fired a multithreaded process but when I see the output on a machine with kernel version 2.4.21-27.0.2.ELhugemem, I see many processes with the same command line. What I got to know is that threads are not treated differently then processes. But surprisingly for another machine with kernel version 2.4.21-27.ELsmp, when i fire 'ps -ef' I just see one entry for the command. I do not understand why such different behavior for different kernel versions? Is it the expected behavior?


Please reply soon with some link to read on and have a proof of...
