Hi Kevin,<div><br></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>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>Greetings,</div>
