You can demo that using a kind of "cpu graph" widget (like 
xfce4-taskmanager) showing that all the cores are at their maximum. It 
proves at least that erl transparently distributes the erlang processes 
on all the nodes.

Not sure to understand.
The program will be limited to the number of erlang processes (some of 
the erlang framwework plus one process for each sieve - adjust erl with 
the +P option) you can run on your machine.
Then if you want to have another machine taking the following sieves in 
charge, and another machine, etc., then the whole program/application 
will have to be redesigned.
