<div>Hi Kevin,</div><div><br></div>What reader are you using to read your data ?<div>Moreover, do you have a descent graphic card with the correct driver installed ? On Linux, this is more than important to take the latest NVidia driver and don't use the system package version.</div>

<div>Hi Sebastien,</div>
<div> </div>
<div>There is a normal ethernet cable with 1 GB/s between server and
computer.</div>
<div>The same data was created with different number of processes, for example 4
times 330 megabyte or 8 times 165 megabyte, so that the data as a whole is 1320
megabyte big and it is an unstructered data.</div>
<div>Well I had not the time to test it again, but I will do.</div>
<div> </div>
<div>But what I haven’t understand is the fact that when I load this data and
want to change the filter from outline to wireframe or surface than my Paraview
crashed after one minute or so. When I load a single part of the data (with
165MB or 330MB) I could change the filter but it needs very long to do
that.</div>
<div>When I first use isosurfaces on the data than I have no problem to view the
data or to move it around. Where could be the problem?</div>
<div> </div>

Kevin,
<div> </div>
<div>How good is your network between the remote PC that execute pvserver and
your client computer that run paraview ?</div>
<div>How big is your data ?</div>
<div>What type of data is that ? Structured or unstructured ?</div>
<div>Did you try to run pvserver on that very same machine without using MPI ?
Does that change anything ?</div>
<div>Did you try to go in ParaView/Edit/Settings and compare "local rendering"
vs "remote rendering" performance ?</div>
<div> </div>

<div>Hello community,</div>
<div> </div>
<div>This is my first e-mail to the mailing list, so I hope I do it right
:-)</div>
<div>And sorry for my english, I try my best to make my mail understandable.
If you can I would be pleased if you answer in german. Also I want you to know
that I haven’t a great knowledge about informatics.</div>
<div> </div>
<div>Well I try to use Paraview on parallel, but I think it doesn’t work right
how I do it.</div>
<div>I use a remote PC on which I will run the Paraview client and a extern
server with up to 48 CPUs and good GPUs.</div>
<div>So I start the server using “mpirun –np ‘number’ ../pvserver” or “mpirun
–np ‘number’ ../pvserver –display localhost:0” (my Paraview is compiled with
openmpi on a linux system). Then I connect over the remote PC in Paraview to
this server (client/server mode).</div>
<div>It works, but not well. I’ve got test data (about 1GB) and it takes about
two minutes to change for example the filter from outline to wireframe. Also
when I want to move the image with drag and drop it takes about five seconds
to rerender it. I think for only 1GB it takes too long for doing this.</div>
<div>Also I’m not sure if my server uses its GPUs or only its CPUs, I don’t
know how to find it out. </div>
<div>Would it be better to use my remote PC only as a display?</div>
<div>Could you tell me how Paraview scales with the number of data sets
and number of processes. Should I use ‘x’ processes to load ‘x’ data sets? Or
is it better to use more processes than data sets (for example: Would it be
better to use 8 processes for loading 6 data sets than using 6
processes?)</div>
<div>Is there another way how I could start my server that it will work
better? Or what can I change that it will work better?</div>
<div> </div>
<div>I hope you can help me a little bit and give me tips how I should use
Paraview on parallel. Thanks.</div>
<div> </div>
<div> </div>
<div>Greetings,</div>
