To dual-core or not to dual-core

Dear Mathematica Experts,

I currently run simulations in Mathematica 5.2 that take on the order
of months to complete. These
simulations all consist of operations like the following:

         1) {a,b,c,...} - {x,y,z,...}
         2) a - {x,y,z,...}
         3) a*{x,y,z,...}
         4) Apply[Plus, Abs[{x,y,z,...}]]

I know that some operations in 5.2 will automatically take advantage
of mulitple cores if they
exist on a machine, splitting up the work automatically across cores
without any custom coding
on the users part, but does this apply to operations like the ones
I've listed above?

Any and all insights are graciously appreciated!

Terry
