If you want to use more than one processor for a single sequential
program, you need to modify code. (or use code modified for multiple
processors).  There is no "magic bullet". (wish there was)

Not yet. A generic algorithm analyser would be nice, but just think
how hard it is to figure out what someones C program is trying to
do.
