[PD] libpd separating gui from core

[Charles Goyard]

Hi,

just to give some example of single vs multi-threaded, and some
comparison points.

- projects like haproxy and lighthttpd show that good state
machine programming can be more efficient that multi-threaded
programming, even on multi-core computers. BUT they handle a much
reduced number of use cases.

- graphics chipsets are massively parallel. They handle huge amounts of
data. BUT they are hard to build, they also handle a much recuced number
of use cases, CUDA and OpenCL being a generalization.

- vvvv (on windows) has its core single-threaded, and a lot of objects
are multi-threaded, just like pd. It suffers the same than pd: when
you get interactive with the GUI, the framerate slows down dramatically.

- whitecat (a DMX software) has its GUI that runs on OpenGL, and it's
not that efficient.

In the case of PD, maybe just a good mix of libpd and a generalization
of pd~ can improve things much.


Take all this as small talk, I don't know much about core pd anyway :-/.


Cheers,
