Hi,
I use version 1.9.0 64 bits on windows (version Panda3D-1.9.0-x64-2014.1.27-503). I have a complex configuration, where I use 3 versions of ppython.exe (a left, middle and right version) to run three channels for 3 displays. In order to optimize performance, I run these on different processors. In the 32 bits version I could simply set each version to a separate processor with imagecfg, but in the 64 bits version of panda that’s not possible anymore. So now I use psexec to set the affinities.
The problem I encounter, is that on some computers occasionally the following error occurs:
the renderer crashes when started by psexec with the following message:
:audio(error): OpenALAudioManager: No open device or context
I know this issue also sometime occurred with panda 1.8.0 and seems to have been solved later, but now I have it again. The computer on which this occurs has an onboard sound chip (no separate sound card).
When I start panda with this:
start /MIN /NORMAL c:\Panda3D-1.9.0-x64\python\ppython_right.exe mainR.py
start /MIN /NORMAL c:\Panda3D-1.9.0-x64\python\ppython_left.exe mainL.py
start /MIN /NORMAL c:\Panda3D-1.9.0-x64\python\ppython_center.exe mainC.py
then there’s no problem or OpenAL error and all works fine, except that I can’t set the processor affinity of the three processes.
When I start panda with this:
psexec -d -normal -a 3,7 c:\Panda3D-1.9.0-x64\python\ppython_right.exe mainR.py
psexec -d -normal -a 2,6 c:\Panda3D-1.9.0-x64\python\ppython_left.exe mainL.py
psexec -d -normal -a 0,4 c:\Panda3D-1.9.0-x64\python\ppython_center.exe mainC.py
I get this OpenAL error on some computers most of the time (not always).
Does anybody know what could cause this ?
