<p class="MsoNormal">Dear All,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I noticed that the Ensight reader encounters problems when running the pvserver on more than ~12 processes. Depending on the code which generated the ensight file, Paraview either crashes while reading the file or reads the geometry but
messes up the variable arrays. I carried out test on the standard naca.bin.case, which comes with the tutorial data. I noticed that the ensight reader already distributes the data over the processes and this might be causing the issue. When opening the naca.bin.case
with 4, 6, 8 or 10 processes I get no errors. If I start the pvserver with 12 processes Paraview hangs while reading the file and reports an error:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span style="font-size:9.0pt">ERROR: In /home/caldron-b/paluszek/linux/Software/Paraview/v5.0.0/ParaView-v5.0.0-source/VTK/Common/DataModel/vtkDataSet.cxx, line 435<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:9.0pt">vtkStructuredGrid (0x1faa690): Point array DENS with 1 components, only has -260 tuples but there are 0 points<o:p></o:p></span></p>
<p class="MsoNormal"><o:p></o:p></p>
<p class="MsoNormal">Strangely it works with 13 parallel processes but I get errors with 14 process and again success with 15 ranks and failure with 16.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The second test case was carried out on the disk_out_ref.ex2 converted to ensight in Paraview. The ensight writer seems to be having issues on its own as is it does not write the *.case file, which is the main ASCII file containing metadata.
Nevertheless it was easy to generate one based on the naca.bin.case. With the converted disk_out_ref I can read the ensight format with up to 12 parallel processes without any issues. With more ranks I am still able to read in the file but the variable arrays
become scrambled. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">With my other industrial enisght files I get either an error while reading the file (log attached) or I read in the files but with scrambled variables. I am using Paraview v5.0.0 compiled from source with system libraries. I got the same
issues with version 4.3 and 4.4 and openmpi, mpich and platform mpi so I am assuming that this is not related with my build. Nevertheless, I would appreciate if anyone could reproduce this behavior.
