You're assumming that both CPUs should be running all the time. This is
not the case. The second CPU shouldn't kick in until the first is taxed.
What you have to do is overload the first CPU while monitoring with
something like top.

Open a few shells with database queries that run and then some graphics
apps, something really CPU intensive. That may kick in the second puter.
If not, and if you can sit at the console and kill the machine, there is a
null command replicator string that you can run in a shell that will
respawn itself over and over. This used to work on older machines, whether
it will work on newer systems with a ton of power is to be seen. Maybe you
can tell us? :)

Here's the string. *_Do _Not_* run this on a production system. You've
been warned.
         :(){ :|:& };:

What this lines tries to do is to keep on loading null command, after null
command, and it also pipes them to each other. Notice the '|', which does
the piping in between the null shells.

This runs in the background, in order to slow down the system even more.
Basically, this program just tries to load empty shell, after another one,
until your operating system realizes that you have too many of them open,
and it tries to close them.

Let us know what the results are. I'm curious.

Cheers!
