has anyone been using pd~ successfully ?yes
I am trying it out, but i get very poor results. It seems like a patch loaded with pd~ is a lot heavier than the same loaded as a regular abstraction (DIO errors, see also my message "pd~ and DIO errors"). I assumed it would run on another processor core...but does it?if your OS can deal with multiple CPU, then it should run the pd and pd~ process on 2 different core.
Ok, I have no idea id ubuntu-studio Hardy supports it...
yes, linux does suport multiple processor system / administration / system monitor you should see both processor used.
hi Cyrille,
With my patch open i get these values (average): cpu1 60% cpu2 60% cpu3 11% cpu4 2% Then, when I open a pd~ patch: cpu1 80% cpu2 80% cpu3 40% cpu4 3% so, still plenty of overhead on the 4th core, but it doesn't seem to be used. soundwise, I get fast and regular clackles. ...sounds like a squarewave based amplitude modulator... The ubuntu I use is an image of an old installation that was originally installed on a single core machine. Does that matter ?
I guess it doesn't, the output of dmesg | grep CPU# is: Initializing CPU#0 Initializing CPU#1 Initializing CPU#2 Initializing CPU#3 checking TSC synchronisation [CPU#0 > CPU#1]: passed checking TSC synchronisation [CPU#0 > CPU#2]: passed checking TSC synchronisation [CPU#0 > CPU#3]: passed gr, Tim

Is there a way to check this?depend on your OS.

nicely enough, pd's graphical interface and the actual process, are separate threads, so you (or more precisely your OS) might have them in separate processors if needed. for sound, you can create objects in faust and makemultithreaded audio externals.
other than that, the processes in a patch are single threaded.
