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.
