On OSX you should make the shm settings much larger. OSX still has the original values (~4MB) from the original mid-80s NextStep. <br><br><div class="gmail_quote">On Tue, Aug 30, 2011 at 5:25 AM, cyrille henry <span dir="ltr"><<a href="mailto:ch@chnry.net">ch@chnry.net</a>></span> wrote:<br>

<br>
you can use multiple pd instance, or use pd~ objects.<br>
This 2 solution aimed to have 2 (or more) pd running.<br>
the 2nd solution is great since all pd instance are synchronized at audio rate.<br>
The 1st is better if some instances can slow down, so that it did not slow the others.<br>
<br>
The main bottleneck is the communication between this process.<br>
for audio communication, prefer pd~ solution.<br>
for huge data communication, i don't find both approach very good.<br>
for image communication, i successfully use pix_share_read and pix_share_write object (for both solution).<br>
<br>

Hello list<br>
Im pushing a Mac quite a lot with image analysis + audio and id like to know if there is a simple way to use efficiently the multiprocessors.<br>
Ive read through a recent paper by Miller concerning multiprocessing, but is there somewhere a manual :) ? Something practical for a basic user ?<br>
Would running two instances of PD (one processing image and the other sound, with some internal bus link) be a good trick ?<br>
Anyone gone along this way ?<br>
Thanks<br>
JM<br>
