to verify make a small job on 1 node. In the shell you are starting
pvserver in, after you've done all the environment settings you need
to to setup for paraview, run "glxinfo" and look for the gl vendor,
gl version and gl renderer strings. these should give you info about
your tesla. that can be done from your batch script or at the
command prompt. some systems like cray mpiexec command (aprun) runs
the program on a different set of nodes than the batch script
itself, so for a system like that run "aprun -n 1 glxinfo".<br>

<br>
Are you by any chance logged in with ssh X11 forwarding
(ssh -X ...)? It seems the error you report comes up often
in that context. X forwarding would not be the right way
to run PV on your cluster.<br>
<br>
Depending on how your cluster is setup you may need to
start up the xserver before launching PV, and make sure to
close it after PV exits. IUn that scenario your xorg.conf
would specify the nvidia driver and a screen for each gpu
which you would refernece in the shell used to start PV
through the DISPLAY variable. If you already have x11
running and screens configured then it's just a matter of
setting the display variable correctly. When there are
multiple GPU's per node then you'd need to set the display
using mpi rank modulo the number of gpus per node.<br>
<br>
I'm not sure it matters that much but I don't think that
you want --use-offscreen-rendering option.<br>

Managed to get a "working version of Paraview-4.2.0.1"
on our GPU cluster but when I try to run the <br>
parallelSphere.py script on more than one node it just
hangs. Work like it is supposed to up to 12 cores on a
single node. I am still trying work out if I a running
on the GPU "tesla- C2070). <br>

The goal is to be able to support batch rendering on the
whole cluster ~96 nodes.<br>
<br>
Also do I need set another environment variable in my
Paraview module to make the Xlib<br>
warning go away?<br>
<br>
[cbording@f100 Paraview]$ mpirun -n 12 pvbatch
--use-offscreen-rendering parallelSphere.py<br>
Xlib: extension "NV-GLX" missing on display
"localhost:50.0".<br>

Xlib: extension "NV-GLX" missing on display

<br>
Is this related to my not being able to run across
multiple nodes?
