if you plan to stay pure-pd, using netsend/netreceive is probly more
efficient for comm between the 2 instances of pd ..

 |I'm helping develop an installation using pd (linux).  We are quite poor,
 |but still manage to have the choice between using a single celeron 533 MHz
 |processor, or a SMP system with two celerons running at 523 MHz.
 |There are four cheap sound cards in this system to give us eight outputs.
 |I think these must all take their input from one pd, as we need to
 |smoothly move between them.
 |The question is this:
 |Is there a good way to take advantage of both processors in the SMP
 |configuration (and would this provide a significant performance gain over
 |a single processor)?
 |Is Open Sound Control (OSC) the only way to do this (run a pd on each
 |processor, with a mixing stage in one of them, and OSC providing the
 |pipe)?  Does anyone know if the overhead associated with OSC would make
 |this a bad idea?  Anything better?  Any simple solutions?
 |I hope some of that made sense.
