My experience with the Fedora Core 4 SMP kernel running on Athlon 64 X2 
(dual core) is that the kernel will schedule individual processes to 
different processors as needed.  If you are running a single process app 
with a single thread, it will run fine on one processor, leaving the 
other(s) to do whatever else needs to be done.

Unless you are doing true parallel processing (like message passing), I 
don't think you need a special build of your applications.
