There could be a hole host of factors, but the best place to find out about trying to get your code to run as best it can on multi core, is head over to the Intel community site here:
http://www3.intel.com/cd/ids/developer/asmo-na/eng/328626.htm It has a hole smack of ideas, code, and checks you can add to your code to help it run better.
