most useful mode since I don't work with huge datasets and my client can perform
all rendering work without having to download several pieces of files that were

bunch of files on the processing machine that don't need to be rebuilt on the
client's machine - for me, it's wonderful.</FONT></SPAN></DIV>

<DIV></DIV>So you are getting the same error when running pvserver and pvclient?
Do me a favor, make sure that there is no DISPLAY enviromnent variable set when
running in ParaView. You may have to unset it in .XXrc to override what ssh
sets. I want to make sure that the reason the server is crashing is due to X not
due to something else. Another way of finding out is to attach to one of the
pvserver processes with a debugger. Also, does this happen when you run a 1 node
server? <BR><BR>-Berk<BR><BR><BR>

see what you mean. My problem is that, unfortunately, we don't have render

Ok. It's clear now. I guess I got confused after seeing what PV compilation
produces. It builds different binaries (pvclient, pvrenderserver, pvserver and
pvdataserver). Firstly I tried to connect the pvclient (on the Windows
machine) with the pvserver (on the Altix system) but I got that error
message (X connection to localhost:10.0 broken (explicit kill or server
shutdown)). After that, I tried to connect pvclient with pvDATAserver and the
problem persisted. I thought it strange since I was just repeating with PV
2.4.3 the same procedure I used to do with PV 2.2.1 (which has been running
nicely in parallel, including with Ensight files which don't work fine with PV
2.4.3). </FONT></SPAN></DIV>

<DIV><BR><BR>Well, mostly because this may not scale well. Polygonal data
generated by 10 nodes might be too big to be handled by a single node. If you
client can handle it, no problem. There is not client/data server scheme. You
either have client/data server/render server or client/server modes. If you
are running in client/server modes, the server is capable of both processing
and rendering. If you don't want the server to render, disable compositing. At
that point, there is no need for opengl or X display on the server.

<DIV><BR><BR>It is not necessary. It is optional. If you are not going to

Unfortunately, there is not pure data server in paraview. All servers have to
be linked against some opengl library, even if it is not used.
