Are you trying to parallize the build, or the execution of the resulting
executable?  If you want to parallelize the build, use "gnatmake -jnnn"
where nnn is the number of concurrent compiles you desire (hint, try 8
on your system).  Assuming you are using the SGI Ada95 product and not
the free FTP distribution, "man gnatmake" will give you all the info you
need.

If you want to parallelize the executable, the SGI implementation will
distribute Ada tasks across multiple processors via the above mechanism.
