When running Pd, it is supposed to run with real-time priority by default, right?
When launching Pd from the terminal, you usually get this printed: priority 6 scheduling enabled. priority 8 scheduling enabled.
I'm running Pd on an Odroid-U3, and launching Pd from the terminal doesn't print anything like this. I'm using Pd with jack, which I run with real-time priority (I'm using Qjackctl and I'm clicking on the Realtime tick-box). I have the following both in /etc/security/limits.conf and in /etc/security/limits.d/audio.conf:
@audio - rtprio 95 @audio - memlock unlimi ted @audio - nice -19
The user odroir (which is the default user in the Odroid image) is a member of the audio group. What am I missing here? Is Pd running with real-time priority indeed, or do I need to do something more than that to run with real-time priority?
Which Pd version do you run? I remember having the same issue with Pd on Raspberry Pi some years ago. Pd at that time asked for rtprio 99 and didn't get it with jackd default settings. In response Miller has then changed Pd's rtprio requirement to 95 (I don't remember which Pd version exactly, it was probably around 0.45). If the Odroid image ships an old Pd, setting rtprio 99 could make the difference.

I'm not sure but I think if Pd is running with jack support compiled in it gets prioriy 6/8 and if not, 95/97 (which is how I originally had set it, but jack imposes its own priority levels).

Hi,
I've proposed pull request #39 (https://github.com/pure-data/ pure-data/pull/39) to fix this (RT status not printed to console any more).
In the meantime, if you don't get related error message (and you don't specify -nrt) then RT should be enabled.

So then, Pd is indeed running with RT?

I'm running the latest Pd (0.47-1) compiled from source with Jack support
on an Ubuntu 14.04 LTS image.

I think so. Try: pd -verbose -stderr
and you should read:
"priority 6 scheduling enabled." if jack support is compiled in, or:
"priority 92 scheduling enabled." if not.
If you hadn't the rights for real time, a simple: pd would print:
"priority 92 scheduling failed."

That did it! I did get the "priority 6 scheduling enabled." message, so it's fine. Thanks!
