Thanks for the reply vbe !

But before I dwell further ,
I have some queries:

In case I run multiple processes from a script ,
1) Are all the processes allocated to a single CPU or multiple CPU ?
2) Can there be a possibility that a lot of time is wasted in scheduling the processes , allocated to single CPU?

3) In case of a fork() , are the child processes allocated to multiple CPUs for execution ? If not , can we do so ?
