[Paraview] Paraview v5.0.0-rc2 with OpenGL2 backend failing to start in parallel

Fri Dec 18 10:00:22 EST 2015

Hi Cory!
Thank you very much for that.
As said earlier in another post, I am very keen to see PV v5.0.0 release so I am happy to help and report issues before the new version gets unleashed.
Cheers,
Frank.

Frank,

Thanks for the info on where you got the code. Maybe there's a problem with the source packaging? I'll try out that download and see if I can reproduce the problem.

Thanks,
Cory

Hi Cory!

I have compiled the source code from the Paraview v5.0.0-RC2 source files that I downloaded earlier this week from http://www.paraview.org/download/.
No GIT repository there and none to be found in the top-level directory of the source files.

Paraview client & server are from the same build, since I am starting both server and client from the same command line on the (Linux) workstation, hence I am using the same environement.

HTH,

Frank.

Hi Frank,

Since you said you recompiled ParaView, I suspect that maybe you forgot to update the submodules ParaView uses. In the ParaView source tree, run

git status

If VTK is listed, it may say there are new commits available for VTK. To update VTK, run

git submodule update

This has been an issue a few folks have encountered in the past.

Also, double-check that your ParaView client and server are truly from the same build.

HTH,
Cory

Dear all!

I recompiled Paraview-v5.0.0-rc2 from scratch using OpenMPI v1.6.5 and GCC v4.7.2 on my workstation.
The QT & Python versions are the default system versions and are resp. 4.8.4 & 2.7.3.

After successful compilation and installation, I start 8 parallel pvserver instances with:
mpirun –np 8  pvserver –sp=7436

Then, I start paraview and connect to the server running on the same machine. After connection is established, paraview fails with a segmentation fault.

Waiting for client...

Client connected.

I have included hereafter how Paraview was compiled:
cmake $sourceDir \
         -DBUILD_SHARED_LIBS:BOOL=ON\
         -DBUILD_TESTING:BOOL=OFF\
         -DBUILD_DOCUMENTATION:BOOL=ON\
         -DCMAKE_BUILD_TYPE:STRING=Release\
         -DPARAVIEW_ENABLE_CATALYST:BOOL=ON\
         -DPARAVIEW_ENABLE_VTK_MODULES_AS_NEEDED:BOOL=TRUE\
         -DPARAVIEW_USE_MPI:BOOL=ON\
         -DPARAVIEW_USE_UNIFIED_BINDINGS:BOOL=ON\
         -DPARAVIEW_ENABLE_WEB:BOOL=ON\
         -DVTK_OPENGL_HAS_OSMESA:BOOL=OFF\
         -DPARAVIEW_BUILD_PLUGIN_SurfaceLIC:BOOL=TRUE\
         -DPARAVIEW_ENABLE_VTK_MODULES_AS_NEEDED:BOOL=TRUE\
         -DVTK_USE_OFFSCREEN:BOOL=OFF\
         -DVTK_USE_X:BOOL=ON\
         -DVTK_USE_QT=ON\
         -DVTK_USE_DISPLAY=ON\
         -DVTK_USE_GUI_SUPPORT:BOOL=ON\
         -DPARAVIEW_BUILD_QT_GUI:BOOL=ON\
         -DCMAKE_INSTALL_PREFIX:PATH=$installDir\
         -DPARAVIEW_ENABLE_PYTHON:BOOL=ON\
         -DPYTHON_ENABLE_MODULE_MPIPython:BOOL=ON\
         -DQT_QMAKE_EXECUTABLE:FILEPATH=/usr/bin/qmake\
         -DPYTHON_EXECUTABLE:FILEPATH=/usr/bin/python2\
         -DPYTHON_INCLUDE_DIR:FILEPATH=/usr/include/python2.7\
         -DPYTHON_LIBRARY:FILEPATH=/usr/lib64/libpython2.7.so<http://libpython2.7.so>\
         -DPYTHON_UTIL_LIBRARY:FILEPATH=/usr/lib64/libutil.so\
         -DVTK_RENDERING_BACKEND:STRING=OpenGL2\
         -DModule_vtkRenderingLICOpenGL2:BOOL=ON

I must have missed something since I guess that Paraview using parallel servers should run, even when there is only one GPU available. Any hints would be greatly appreciated.

Best regards,

Frank Albina
