<p>Dear all, </p>
<p>I have installed Paraviewweb on an Amazon EC2 GPU instance based on the installation guide at:
</p>
<p><a id="lnk652604" href="http://www.paraview.org/ParaView3/Doc/Nightly/www/js-doc/index.html#!/guide/paraviewweb_on_aws_ec2">http://www.paraview.org/ParaView3/Doc/Nightly/www/js-doc/index.html#!/guide/paraviewweb_on_aws_ec2</a>. The webpages under "apps"
can show up correctly. Now I am trying to install the parallel visualization. Here are a few questions I want to verify:</p>
<p><br>
</p>
<p>1. When I run pvpython on the GPU instance, I got the error message saying "bad X display..". I guess this occurs when the instance does not have a "real graphics" card and "off screen rendering" option should be used. My question is will this error affect
the Paraviewweb application?<br>
</p>
<p><br>
</p>
<p>2. I have installed Paraview (not Paraviewweb) on two other instances (without GPU) which run MPI without any issues. I would like to use those two instances as a part of the parallel visualization framework. Should I install the Paraviewweb on those two
instances as well? Or I just need to change the machine configuration file to include the two instances?<br>
</p>
<p><br>
</p>
<p>3. It seems GPU is needed for the instance when I configured the Paraviewweb on Amazon EC2. There is a option for NVIDIA.. But I read this document:</p>
<p><a id="lnk220245" href="http://www.paraview.org/ParaView3/Doc/Nightly/www/js-doc/index.html#!/guide/os_mesa">http://www.paraview.org/ParaView3/Doc/Nightly/www/js-doc/index.html#!/guide/os_mesa</a> which says GPU may not be necessary. Is this applicable to
Amazon EC2 instances?<br>
</p>
<p><br>
</p>
<p>4. Launcher (</p>

pw.session.public.fields</strong> if I am going to use the default Parallel example provided by Paraviewweb to start with.
<br>
</p>
<p><br>
</p>
<p>Sorry about throwing out so many questions but Paraviewweb is a very interesting application to explore.
</p>

<p>Thanks, </p>
