Is Ghost multi-threaded?

Can someone tell me if Ghost 15 is multi-threaded?  That is, is the software specifically written as multi-threaded to take advantage of multi core/thread processors?  If so, does anyone know how it works and if any of it is user configurable.  Also, I know Ghost will run on 64 bit Windows 7, but is Ghost itself 64 bit software?

 

I also have the same questions about the lastest version of NAV. 

 

Thanks
