I installed OpenCV library for a video application.
I write a program a run it. It works very well.

My question is : Can i use both of my ARM cores for running an OpenCV application.
If possible, how can i do it???

Excuse me if my question seems naïve but i'm really new on Parallella

This is not a Parallella-related question. :-)

Yes, you can use multiple CPUs in a Linux environment if you use multiple threads or multiple processes. Also, OpenCV has a parallel_for construct, which you should be able to use. From a pure software/Linux point of view, the ARM side of the Parallella does not differ significantly from any other Linux on a PC.

Please see my reply to your post in another forum, and also if you could please refrain from posting the same question to multiple forums.
