[pd~] is for splitting the DSP part into separate threads in a closely synced
way ... if you have clearly independent parts of your patch and you want to run
it on several cores often it makes more sense to run a few instances of pd,
passing information between them using the local network ports. Eg if you have
GEM and audio parts this is often the way to go. Pd-gui essentially runs the
interface, though I understand the separation between the two isn't as clean as
it could be. Audio and message processing is done in pd.
