Thankyou for a very helpful response.
That clears up a lot for me.

Yes they do if I run the client on the same machine as the server. If I
run the client on a windows machine (or any other machine for that
matter) in this mode I get a whole bunch of VTK socket communicator
errors (if I spent half a day problem solving this I could probably
work it out but for now I am happy with a quick fix). When I run in
just server/client mode (no render server) I can put the client on any
machine I want.
If the server/client mode also supports distributed rendering then it
seems that the only use for seperating out the render-server is to be
able to use different machines for the different tasks. Is this correct
or am I missing something?

I have been using Paraview's inbuilt filters and shapes to try and
simulate operations on a large dataset...the codebase we are working on
is not yet mature enough to produce any large datasets yet...I am
charged with getting the 'distributed' infrastructure ready. So
basically I don't know...So far I can only see activity on the
render-server side but this could just be because I am not giving it a
hard enough time on the computation side of things. Is there a known
test that is both computationally intensive and rendering intensive that
would be a huge help? ...at the moment I have just been chucking a load
of paraviews own filters at its own objects but this usually takes only
a few seconds and sometimes crashes the machine the server is running on.
Also I got the impression that it was difficult to use the GPU's to do
rendering. But it seems that the tiled windows that are popping up on
my server are in fact using opengl if I am to believe there titles that
run somthing like "opengl window". Does this mean that the rendering is
being done by opengl (and therefore probably the GPU) and that if I had
fast graphics cards in all my nodes the rendering will go much faster?
I am also getting an error message sometimes in the clients terminal
window which runs 'xlib: extension "xfree86-DRI" Missing on display ":0.0"'.
This could be that I have made an error during compiling paraview, I did
use 64bit GL libraries, could this be the problem?
Thanks again for the response Amy
