Hello pd-folks!
I have a problem someone might have a solution to. Same pd-patch giving wildly different results on 2 machines.
Using a section of several [vibraphone~] objects from the percolate-lib, PD eats all my cpu, pushing it above 90%, and destroying sound. The machine is a Dell 5150, with 2.8GHz cpu.
The same patch runs clean (stays around 20% cpu) on another machine here, with slower cpu! (somewhere around 1.4GHz)
The computer giving me aches is a Dell laptop, inspiron 5150, running fedora core 2, with planetccrma-low-latency kernel.
uname -a: Linux localhost 2.6.7-1.437.1.ll.rhfc2.ccrma #1 Thu Jun 17 10:45:42 PDT 2004 i686 i686 i386 GNU/Linux
Pd is:
CVS-version: Pd version 0.39 TEST 0 Planet-CCRMA-version: Pd version 0.37.1 devel
Tried with pd from planet-ccrma and latest cvs-version compiled on this machine. Both the percolate-lib coming with the ccrma-dist, and one i built from a src.rpm on this machine. Same result whatsoever.
Ive tried shutting of the 'cpuspeed' process to keep the latptop running at full speed all times, but it didnt do much with the problem. Pd very soon hits 97-98% and stays there. Only save is to run pd -r 22050, where the patch runs around 40-50%.
Anybody got a clue?
Thanks,
-anders
