has anyone been using pd~ successfully ?<br>
<br>
yes<br>
<br>
I am trying it out, but i get very poor results.<br>
It seems like a patch loaded with pd~ is a lot heavier than the<br>
same loaded as a regular abstraction (DIO errors, see also my<br>
message "pd~ and DIO errors").<br>
I assumed it would run on another processor core...but does it?<br>
<br>
if your OS can deal with multiple CPU, then it should run the pd and<br>
pd~ process on 2 different core.<br>
<br>
<br>
Ok, I have no idea id ubuntu-studio Hardy supports it...<br>
</blockquote></div>
yes, linux does suport multiple processor<br>
system / administration / system monitor<br>
you should see both processor used.<div class="im"><br>
<br></div></blockquote><div>hi Cyrille,</div><div>With my patch open i get these values (average):</div><div>cpu1 60% cpu2 60% cpu3 11% cpu4 2%</div><div>Then, when I open a pd~ patch:</div><div>cpu1 80% cpu2 80% cpu3 40% cpu4 3% </div>
<div>so, still plenty of overhead on the 4th core, but it doesn't seem to be used.</div><div>soundwise, I get fast and regular clackles. </div><div>...sounds like a squarewave based amplitude modulator...</div><div>The ubuntu I use is an image of an old installation that was originally installed on a single core machine.</div>

hey vedran,<br>
pd~ is a way of opening another instance of pd from within a<br>
patch.<br>
<br>
ideally you want gem and sound on separate instances<br>
(connected via<br>
udp, pd~ or some other way). each of these processes will use one<br>
processor.<br>
<br>
nicely enough, pd's graphical interface and the actual<br>
process, are<br>
separate threads, so you (or more precisely your OS) might<br>
have them<br>
in separate processors if needed.<br>
<br>
for sound, you can create objects in faust and make multithreaded<br>
audio externals.<br>
<br>
other than that, the processes in a patch are single threaded.<br>
<br>

Hi!<br>
can someone tell me if one instance of pd (with gem) can use<br>
more than one core on multi-core processor?<br>
