Help
I have a multicore computer and when I use a program that take a lot of resources I see that only 1 of the cores is maxed out and the others are doing nothing. I was wondering why that is?

Its possible that the program your running only has one thread (is not "dual core" or "multi core" optimized, which would be why only one core is running.) Try a program like Prime95 with as many threads as you have cores and see if the other cores activate. Multiple cores allows you to simultaneously run multiple threads. If you only have on thread it will only use one core. Only a suggestion tho, im currently taking my A+ certification (still learning) so my answer may not be what your asking for.

To add to this excellent answer, any program must be programmed to be SMP or Symetric Multiprocessing aware. More information on what SMP is can be found here: http://www.networkworld.com/details/550.html?def
