han,
by any chance would you be talking about NSThread? You want to break
a process off into another thread to complete your calculation then
notify your application when it is completed. This will not hold up
the UI while doing the calculation.
I am not sure how to implement it as I am still new but NSThread seems
to be what you are looking for.

I don't know how to create a faceless background application?
thanks.
