This isn't following my sense of how multi-processing works. A single
thread cannot load balance. To get distribution of the audio processing
you'd have to create multiple threads that can operate in parallel (a
good place might be on the connections to a mixer) and have the
rendering for the input nodes done in separate threads then synchronize
the rendered buffers during the mixing process.
Am I mistaken?

Unless you pull audio from it yourself, an AUGraph renders on the
CoreAudio IOThread, and since that thread can only run on one CPU at
a time, an AUGraph will not normally distribute across CPUs.

Failure is not an option. It is a privilege reserved for those who
try.
