unfortunately, we don't have render clusters here. Thus, we must try to work
with the Altix as it was only a parallel data server connected to a
Windows XP client machine performing all rendering work with its NVidia
Quadro FX 4400 video card.</FONT></SPAN></DIV>

color=#0000ff size=2>Renato: 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>

this case.</BLOCKQUOTE>
<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. <BR></DIV><BR>

2) Compile the server with Mesa (note: the client should never be<BR>compiled

compile PV with Mesa<BR>support in a system without rendering

<DIV><BR><BR>It is not necessary. It is optional. If you are not going to render
anything on the server, compile with whatever opengl library you want.
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.
