[Paraview] Re: Unable to connect to pvserver running in parallel

[KLemons at beckman.com]

The key to this for me was to make sure I had it compiled with offscreen 
rendering, and then starting the server like this: (node01 is the main 
node)

node01> mpirun -np $PROCS `which pvserver` --use-offscreen-rendering 
$PVSERVOPTS &
[ output truncated ]
node01> pvclient $PVCLNTOPTS

mpirun takes care of migrating the paraview server onto the other nodes 
and making sure they're connected to one another properly, while the 
offscreen rendering switch enables it to do the rendering without 
connecting to an actual X display (via chromium, I believe) and then 
combined onto a single display on the client.  I spent some time messing 
around with the cmake configuration, so you might have to poke around 
there a bit too.

Hope this helps,
~Kyle
