color=#0000ff size=2>In your case (1 client) pvserver IS a data server. In fact
it the best of both worlds, it's a data server until the polygonal
data gets to big (passes the 10MB threshold) and then it becomes a
render server, and you can dynamically change that threshold....or if for some
bizarre reason you never want it to become a render server (not sure why.. but
whatever) you can just turn compositing off and it will always be a data
server.</FONT></SPAN></DIV>

folks out there, splitting the server into a data server and a render server is
a more complex, less effective solution, then just running pvserver and
pvclient. If you are running pvdataserver and pvrenderserver you should have a
REALLY good reason for doing so.</FONT></SPAN></DIV>

have a bunch of files on the processing machine that don't need to be rebuilt

<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>

I see what you mean. My problem is that, 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>

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. <BR></DIV><BR>

2) Compile the server with Mesa (note: the client should never

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