Erlang and multi processors

[Hakan Stenholm]

How does Erlang deal with multi processor machines (i.e. more than one
CPU in the same machine) ?
Does spawn/3 get distributed  on the CPUs or is spawn/4 needed - one
node per CPU  which would imply that one Erlang VM is run per CPU (which
seams a bit costly if one has many CPUs) ?

ps: how does one relpy to questions on the mailling list so that the
answear appears on the list ? - mails to erlang-questions@REDACTED  as
