i used "chmod +s /usr/local/bin/pd" as "su" then runned:
huolong@linux:~> pd -alsa -alsadev 1,2 -nomidi -rt Sample width set to 2 bytes priority 96 scheduling enabled. memory locking enabled. priority 98 scheduling enabled. memory locking enabled.
pd starts and audio worx... so, does my suse8.1 have a RT kernel or is pd just emulating
thnx -andre

hi,
how do i use "-rt" flag as user ? tried "su" but i get command not found where ever i run it (/usr/bin ; /usr/local/bin)
cheers -andre ps. i used "make depend" + "make install"

It seems to work. If you want "better" realtime, use a kernel with the low latency patches.

Pd runs with "realtime" even on an unpatched plain vanilla kernel. The low latency patches just lower the chances, that the kernel itself will interrupt you audio processing.

Hi
http://www.linuxdevices.com/articles/AT8906594941.html
some details and tests about the chances of the kernel interrupting pd preemptive patch / low-latency patch
Has anyone experience with a kernel with both patches applied and pd?

If you want to run pd together with jack the patches are definitely necessary, otherwise jack will not run without producing underruns.
Especially the low-latency patch improves the situation a lot on a loaded system (e.g. if you want to read/write from harddisk in you patch).
