Parallel running quicksort

I'm still very new to multithreaded programming. I want to have my quicksort to run parallel I have most of it working but when I run it, the result is not really as expected. It basically sorts perfect but result would end up being something like 0,0,0,1,2,3,4,5,5,6,2,2,3,3,4,5,6,6,8,9,9. Im comparing the results between sequential and parallel.

Thank you

This is my code:

UseCodeTags when you post code. Use EDIT option and put code fragments.
