[Paraview] misinterpreted VTK files in parallel pvserver

[Michal Kulczewski]

Hi,

I have problems with reading VTK files in parallel version of ParaView 
in client-server mode. I've made ParaView (3.8.1) to use OSMesa (7.5.2) 
for offscreen rendering. The VTK dataset is correctly interpreted and 
displayed in serial version of pvserver (also using offscreen rendering 
with OSMesa). However when I switch to parallel version of pvserver, the 
VTK data is misinterpreted. For example, the volume rendering is not 
correct, and the Counter filter gives quite different (and invalid) 
range value than the serial version does.

The VTK dataset is represented in serial XML file format, with data 
array written as base-64 binary encoded data. I guess the 'endian' issue 
is not the case when VTK files are XML-based.

The dataset is well distributed over nodes in parallel pvserver (checked 
with Process ID Scalars filter).


Does anyone have a clue what might be wrong then?
