[chuck-users] spork~ and multiple cpus

[Spencer Salazar]

Hi Vilbjørg,

ChucK does not spread processing load for multiple shreds over multiple
CPUs/cores -- all shred and audio processing occurs on a single logical
core. This is mainly because ChucK makes several strong guarantees about
the timing between shreds and audio processing, and these are difficult to
maintain across multiple cores.

Its not uncommon to run multiple chuck instances if multiple-core
utilization is necessary, using OSC to communicate data between them. You
lose a lot of the power of shreds in ChucK, but as I mentioned these
attributes are difficult to implement with multi-core awareness anyways.
