<div dir="ltr">Cool! Thanks - I'll try that. I tried just loading a few vti files anyway running the pvserver under mpirun on the multi-core machine. This machine has no GPU and I got a lot of "swrast" errors (one per core). So I think I don't have a good OpenGL on this machine. I tried building my own Mesa OpenGL according to <a href="http://www.paraview.org/Wiki/ParaView/ParaView_And_Mesa_3D">http://www.paraview.org/Wiki/ParaView/ParaView_And_Mesa_3D</a>, but got compilation errors using the newest version of llvm. Then I had to move on to other things. Not sure if you've tried this - maybe you have some ideas. Anyway, I hope to try this again sometime this week. --- Adam</div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div><div style="font-size:12.8000001907349px"><i><font color="#999999">------</font></i></div></div><div><i><font color="#999999"><br></font></i></div><div><b><font color="#3d85c6">Adam L.

<div dir="ltr">Hi Adam,
<div><br>
</div>
<div>The PVTI file format should work perfectly for this application. The PVTI file is an XML file that specifies the different pieces in the whole image and points to the VTI images that contain the pieces. When loaded, each piece should land on a different
CPU - if you are running 12 CPUs. The extents in your VTI files need to be defined in terms of the overall image extent - if they aren't you'll need to modify them so that they are.</div>
<div><br>
</div>
<div>I have attached an example PVTI file with four associated VTI files that you can use as a model to define your own PVTI file.</div>
<div><br>
</div>
<div>Please let us know if you have any trouble.</div>
<div><br>
</div>
<div>Thanks,</div>
<div>Cory</div>

<div dir="ltr">Hi - I have 12 fairly large vti files (each one is a simulation of part of the magnetic field of my particle physics detector). Each file covers a distinct part of the total volume, so that all 12 together covers the whole thing. This would seem
to be a perfect opportunity to try to parallelize Paraview's handling of these files - one CPU per vti file. I have a machine with lots of cores at my disposal. Will Paraview recognize by itself that it can parallelize its operations, one CPU per vti file,
or do I need to do something to make that happen? There's no overlap between the files - will that be a problem? My plan is to run a pvserver on the many-core CPU machine and connect to it via my Mac. Any advice would be helpful and appreciated! Thanks! --
Adam
