<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>Hi Ken,<br>
Thanks for the clarification. I think a little more information is needed
as I am<br>
running into some problem that I can't seem to resolve.<br>
<br>
I am using 3 machines of my cluster all three are connected to 3 displays. I
want <br>
use 2 of them as multi-tile display with 2 tiles. I have the Paraview GUI on
the <br>
third machine. All three have X servers running and are MPI enabled. So here<br>
is how I launch the jobs on the machines.<br>
<br>
$ mpirun -n2 -hostlist "sva11 sva12" /bin/env DISPLAY=:0 pvserver
-tdx=2 -tdy=1 <br>
<br>
and I launch the client <br>
<br>
$ paraview<br>
<br>
and then connect to sva11.<br>
<br>
My servers.pvsc looks like<br>
<br>
<Servers><br>
<Server name="builtin" resource="builtin:"><br>
<ManualStartup/><br>
</Server><br>
<Server name="fw-sva10"
resource="cs://sva10:11111"><br>
<ManualStartup/><br>
</Server><br>
<Server name="fw-sva11"
resource="cs://sva11:11111"> <br>
<ManualStartup/><br>
</Server><br>
<Server name="fw-sva12"
resource="cs://sva12:11111"><br>
<ManualStartup/><br>
</Server><br>
<Server><o:p></o:p></span></font></p>
<div>
<p class=MsoNormal style='margin-bottom:12.0pt'><font size=3
face="Times New Roman"><span style='font-size:12.0pt'><br>
But the window multi-tile window appears only on sva11 and it doesn't<br>
span the whole screen (which it used to do previously). And it doesn't seem<br>
like sva12 is even doing anything. I suspect this because sva11 flickers <br>
when the client connects, but sva12 remains as it is.<br>
<br>
If I do the reverse and connect the client to sva12, then model window appears<br>
on sva12 and sva11 seems to do nothing.<br>
<br>
Is there anything I am missing ? <br>
I am using Paraview 3.2.1.<br>
<br>
Thanks,<br>
Manju<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>What you are trying to do does not work because ParaView is not
supposed<br>
to run like that. When running in client/server mode, ParaView connects<br>
to process 0 of the server, and nothing else. All communication with the <br>
client goes through process 0, and process 0 of the server uses the MPI<br>
interconnect to pass data to and from the other nodes in the server.<br>
<br>
ParaView is implemented in this way for convenience and scalability. It <br>
is not scalable to have every process in the server to connect to the<br>
client because all communication will eventually have to go through the<br>
same network interface on the client side. Also, the MPI interconnect on <br>
the server is almost always faster than the socket communication between<br>
client and server.<br>
