Hi Simon,<div><br></div><div>Yeah, there is documentation on ParaView running on tiled display mode. You can read old posts in the mailing list regarding the topic or read the instructions in this site (<cite><a href="https://visualization.hpc.mil/wiki/" target="_blank">https://visualization.hpc.mil/wiki/</a><b>Paraview</b>_<b>Tiled</b>-<b>Display</b>_Mode). <span style="font-style:normal">It seems like the site is currently off line, but you can still read it on Google's cache. </span></cite></div>
<div><br></div><div>We use a rendering cluster where each node gets one of the tiles, so we are using distributed rendering. Basically, what you do for setting up the tiled display mode is running pvserver in parallel mode (using MPI, you have to compile ParaView from source in order to enable MPI support) in the following way:</div>
<div><br></div><div>mpirun -np XX --hostfile PATH_TO_HOSTFILE /bin/env DISPLAY=:0 pvserver --server-port=PORT -tdx=xTiles -tdy=yTiles</div><div><br></div><div>where XX is the number of processors that you are going to use to run pvserver, PORT is the port number you want to use to bind the server, xTiles is the number of screens you are going to use in the X dimension, and yTiles is the number of screens you are going to use in the Y dimension. For example, for a 3 * 2 tile screen you will use -tdx=3 and -tdy=2</div>
<div><br></div><div>You have to remember two things when you are configuring such a setup. First, you have to configure the xhost in each participant computer to receive incoming connections from the other computers in the visualization cluster, otherwise the setup will not show anything. Second, you have to configure a hostfile where each node gets one screen in the correct order. For example, for the previous configuration I would use something like this:</div>
<div><br></div><div><div>192.168.85.6 slots=1</div><div>192.168.85.4 slots=1</div><div>192.168.85.2 slots=1</div><div>192.168.85.5 slots=1</div><div>192.168.85.3 slots=1</div><div>192.168.85.1 slots=1</div><div><br></div>
<div>That would be the hosts file. It is organized in such a way that the first computer (192.168.85.6) gets the upper left display, while the last computer gets the bottom right display. It is better explained in the previous link, so please have a look at that site.</div>
<div><br></div><div><div>In the other hand, I don't know if pvserver supports stereo. How is your stereo visualization setup? Did you connect to a server or did you use the paraview client directly without connecting to a server?</div>
<div><br></div><div>Thanks a lot for your help.</div><div><br></div><div>Best Regards,</div><div>Andrés Padilla</div><div>Universidad de los Andes, Graduate Student</div></div><br><div class="gmail_quote">2009/5/19 Simon Su <span dir="ltr"><<a href="mailto:newsgroup4ssu@gmail.com" target="_blank">newsgroup4ssu@gmail.com</a>></span><br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi Andrés,<br><br>So you have paraview running in your tile display with -tdx and -tdy options? are they documentation on this? Can you point me to it? Thanks. Does it do distributed rendering (each cluster node is responsible for reading the data and rendering the portion of the whole rendered dataset (resulting image)) or is it just one big machine doing all the rendering and then the rendered image got split and display on the machine running the tile display.<br>
<br>On stereo issue, we have used paraview version 2.6 with modification that we did by one of my ex-colleague. I am not sure about the stereo option in the newer version of paraview. Active stereo for Paraview Version 2.6 worked flawlessly on our SGI prism system. I can send you the source code of paraview 2.6 with stereo modification that you can compile yourself if you like. From what I heard from my ex-colleague, the changes never got made to the repository.<br>

We have configured the tiled display visualization using -tdx and -tdy without problems, but we are wondering how to configure our tiled display with stereo support. We have read that you change some lines in the ParaView code in order to support stereo, and then run paraview with the --stereo option, but we have not found such an option in pvserver. Is there any way to configure the pvserver with tiled display and stereo support? Thanks a lot in advance for your help.<br>
