[PD] Using dual processor to manage 2 Pd at the same time

Any idea on how to get the first Pd working with one  processor and the second with the other?

I'm using the Arduino firmata to trigger both sound and video. I think I can't open twice the same port! So how can I use the OSC then to sync the triggering!?

No, it doesn't mean that.

But all the messages and signals circulate in a since thread (on a single cpu) unless you use special tools to split it into several threads.

Then there is the "client process", which "own" the patch windows and the main window. This runs separately.

Also, [soundfiler], some GEM input/output classes, and much of PDP, can run in an alternate thread.

No idea... I still run a single-core all day long.
