Hi Jeff,
It really sounds like you are unintentionally using X forwarding. It
could be baked into your ssh config or a bash alias.
I see the window with the gears
if you are really doing remote rendering, you won't see the window.
you may be able to confirm accidental X forward using ssh with -vv
option. there would be a bunch of X connection messages if it was in use.
also output of glxinfo may have some useful info. When I have remote
rendering setup I see
name of display: :0.0
display: :0 screen: 0
direct rendering: Yes
with ssh -X
name of display: localhost:10.0
display: localhost:10 screen: 0
direct rendering: No (If you want to find out why, try setting
LIBGL_DEBUG=verbose)

Jeff,
Can you make sure the "Remote Render Threshold" is set to 0?
It is
Also, do you have an X server running (and accessible) on the backend
nodes? You're not using "ssh -X" to login to the backend nodes, right?
I do start an X server on the backend (and I don't use ssh -X).
However, when I test the configuration using glxgears,
I see the window with the gears but they don't turn even though the
app tells me how many frames
it rendered every 5 seconds.
My setup goes from my desktop (with GPU) through a front-end node
(without GPU) to the backend (with GPU). Maybe some additional
configuration is needed.
It seems like I need to get glxgears working properly before I try
Paraview. What should I try? Thanks.

Hi. I created a VTK unstructured grid (.vtu) file for a 500 by 500

point data set. In order to visualize it, I fire up 8 pvservers on
my GPU
multicore backend node using:
mpirun -np 8 pvserver --client-host=XXX --use-offscreen-rendering
and connect to the root server from my ParaView client. I then open
my vtu
file and hit apply, I can see the file gets read in, and then
nothing much
else happens except X on my client grows to fill all of memory, and my
client system (my desktop) becomes unusable. I'm guessing that the
client is
getting overwhelmed with X requests.
What am I doing wrong, and how to fix?
Thanks.
