[Paraview] MPI-aware reader plugin only has rank 0

[Schlottke, Michael]

I do have multiple installations/builds. However, I don’t know how/if they could affect the execution of the paraview executable I’m using: both paraview and pvserver reside in the same (correct) directory on the PATH, and there’s nothing ParaView-related in the LD_LIBRARY_PATH. The only other variable I’ve found is PARAVIEWDIR, which was indeed pointing to an older installation; however, changing it to my installation did not change anything either.

The only other way I can think of how my installation could be affected is that the PARAVIEWDIR variable being set to a ParaView 3.x installation during build/install time and/or that I am using a Python installation in a non-standard location (specified during configure as follows; the Bash variables $PV_SRC, $PREFIX and $PYTHON27 are set to valid paths):

  CC=gcc CXX=g++ cmake $PV_SRC \
    -DBUILD_DOCUMENTATION:BOOL=ON \
    -DBUILD_SHARED_LIBS:BOOL=ON \
    -DCMAKE_BUILD_TYPE:STRING=Release \
    -DCMAKE_INSTALL_PREFIX:PATH=$PREFIX \
    -DPARAVIEW_ENABLE_PYTHON:BOOL=ON \
    -DPARAVIEW_INSTALL_DEVELOPMENT_FILES:BOOL=ON \
    -DPARAVIEW_USE_MPI:BOOL=ON \
    -DPYTHON_LIBRARY:FILEPATH=$PYTHON27/lib/libpython2.7.so \
    -DPYTHON_INCLUDE_DIR:PATH=$PYTHON27/include/python2.7
