Internode process spawning happens explicitly, last I checked. It's pretty easy once both nodes are communicating, but not automatic.
In contrast, BEAM's SMP support is automatic AFAICT; the scheduler will happily distribute processes across as many cores as it can access (1 BEAM thread per hardware thread by default, so a quad-core CPU with one thread per core and a dual-core CPU with two threads per core will both be loaded with four BEAM threads unless BEAM is configured to do something else).
