Hi i am having few queries .

1. Is there any way to allocated processors dynamically or dedicatedly to a particular application or a package ?

2. Is it possible to do it by using PRM

If I understand you correctly, you are asking if you can dedicate a procesor/processors to a process or an aplication's processes.
There a few ways you can do this:
1) Use Psets
2) Use PRM
3) Use WLM (which uses PRM)
4) There are system calls (cannot remember what they are) to give cpu affinity to a process

The system call is mpctl(). Man mpctl for details.
