The dirty pixels might caused if you're exceeding the max screen
size a configured in your server's xorg.conf. That's one way I've
seen that before. You could run xrandr command to list the
available resolutions.<br>
<br>
Not sure about 2, but I've used PV 4.0.1 on an system that has 2
gpu's per node. similar to what you've done. I'm assuming you have
an x screen for each gpu. are you able to run some other x program
per gpu? if yes could you get a stack trace?<br>

<pre wrap="">Hello
I am configuring a new cluster with two GPUs per node. When doing server-side rendering, I get the following dirty pixels when I increase pixels resolution beyond a certain threshold. this is using a single GPU per node with a command like
mpiexec -n 8 -env DISPLAY :0.0 /apps/castor/ParaView/4.0/bin/pvserver -rc -ch=148.***.***.*** -sp=11111
my PV is compiled with ICET_USE_OPENGL:BOOL=ON. What could cause these dirty pixels? my driver is libGL.so.319.17
Second problem: I'd really like to use both GPUs. I run (for example)
mpiexec -n 8 -env DISPLAY :0.0 /apps/castor/ParaView/4.0/bin/pvserver -rc -ch=148.***.***.*** -sp=11111 : -n 8 -env DISPLAY :0.1 /apps/castor/ParaView/4.0/bin/pvserver -rc -ch=148.***.***.*** -sp=11111
and the whole thing crashes right on init with
ERROR: In /apps/eiger/src/ParaView-v4.0.1-source/VTK/Parallel/Core/vtkSocketCommunicator.cxx, line 812
vtkSocketCommunicator (0x200d5f390): Could not receive tag. 144432
I have search the ML and the wiki, but most messages refer to tiled displays, wheras I just want to distribute GPUs over pvservers. What have I forgotten? I am running 4.0.1.
