Wylie, Brian,<br><br> Thank you very much.<br> And I have another question :)<br>"1) The servers (renderservers) can either send images or geometry to the<br>client. If you look under 'View... 3D View Properties' you will see a<br>slider for Composite. If you move slider to zero megabytes you will<br>either get images streaming down from the servers or you will get a<br>crash. "<br>-- You mean the user decides where the rendering process occurs by <br>setting the composite slider? <br><br> In the page 90 of The Paraview Guide (chapter 12 Parallel ParaView), <br>there are some words as follows，<br>"ParaView has the option of using parallel rendering on the render server <br>or rendering directly on the client workstation. ParaView automatically chooses<br>a rendering strategy to achieve the best rendering performance. Smaller models <br>are rendered on the client, and distributed rendering is used for larger models."<br>-- so, I guess that ParaView's automatic choice is based on the user's decision by <br>setting the composite slider. If I move slider to 10 megabytes, the servers send images to the client when the polygonal representation is larger than 10M, <br>and send geometry when it is smaller than 10M. Right?<br><br><br> <br><br>======= 2005-07-11 06:22:03 =======<br><br>Well I'm not Berk but I may be able to help. :)<br><br>1) The servers (renderservers) can either send images or geometry to the<br>client.

If you move slider to zero megabytes you will<br>either get images streaming down from the servers or you will get a<br>crash. <br><br>If you get a crash it means that you servers are not set up so that they<br>can open up X windows. Note that this is a fairly common problem and you<br>have to have your cluster admin (or yourself) change the X server<br>security setting to allow you to do this.<br><br>2) On the servers. The whole point is not to move the data, so wouldn't<br>be useful anywhere else. :)<br><br>3) Same answers for 1 and 2 but should be much faster when using<br>compositing on big data. :)<br><br><br><br>Brian Wylie - Org 9227<br>Sandia National Laboratories<br>MS 0822 - Building 880/A1-J<br>(505)844-2238 FAX(505)845-0833 <br> ____ _ __<br> / __ \____ _________ | | / (_)__ _ __ <br> / /_/ / __ `/ ___/ __ `/ | / / / _ \ | /| / /<br> / ____/ /_/ / / / /_/ /| |/ / / __/ |/ |/ /<br> /_/ \__,_/_/ \__,_/ |___/_/\___/|__/|__/<br><br> Unleash the Beast<br> <br><br> -----Original Message-----<br> From: paraview-bounces+bnwylie=sandia.gov@paraview.org <br> [mailto:paraview-bounces+bnwylie=sandia.gov@paraview.org] On <br> Behalf Of Panfeng Wang<br> Sent: Sunday, July 10, 2005 7:15 AM<br> To: paraview@paraview.org<br> Subject: [Paraview] Berk, help me plz<br> <br> Berk,<br> Given an environment as such:<br> a 4-nodes cluster server without graphics card and a <br> client node with a graphics card,<br> paraview-2.0.1 runs in the client/server mode.<br> <br> My questions are :<br> 1. what does the renderserver send to the client? <br> pixel images for display? Or OpenGL control flows, then the <br> client composites and translates them to pixel images and displays? <br> 2. paraview uses sort-last compositing algorithm, and <br> where does the compositing process occur? on the <br> renderservers or the client? <br> 3. If my environment changes and every server node has <br> a graphics card, then what is the answer of question 1 and 2 ?<br> <br> <br> Thanks<br> <br> <br> Wang <br> <br> <br> <br> _______________________________________________<br> ParaView mailing list<br> ParaView@paraview.org<br> http://www.paraview.org/mailman/listinfo/paraview<br> <br><br><!-- footer --><br><br><br>
