Issue with actual rendering under Catalyst

In Situ Support
1

Hi,

I am getting error like double free or corruption (fasttop) when I try to render a very simple image with ParaView Catalyst. The trace looks like following (sorry I did not compile paraview or catalyst in debug mode yet to see the actual lines but if it is required I could work on it. The same code is working with gridwriter.py script provided by ParaView Catalyst without any issue. I also tried with replacing catalyst_conduit_node_set_path_external_* calls with the catalyst_conduit_node_set_path_* once in case of issue about sharing pointers between simulation code and catalyst but still getting same error. I wonder if I am missing something in here.

For your reference, I am building ParaView using super build with following options,

cmake -DPARAVIEW_EXTRA_CMAKE_ARGUMENTS="-DVTK_OPENGL_HAS_OSMESA=ON;-DVTK_USE_X=OFF;-DVTK_DEFAULT_RENDER_WINDOW_HEADLESS=ON;-DPARAVIEW_USE_QT=OFF" -DUSE_SYSTEM_catalyst=ON -DUSE_SYSTEM_zlib=ON -DUSE_SYSTEM_python3=ON -DUSE_SYSTEM_mpi=ON -DENABLE_osmesa=ON -DENABLE_mesa=OFF -DENABLE_catalyst=ON -DENABLE_fortran=ON -DENABLE_mpi=ON -DENABLE_python3=ON -DCMAKE_INSTALL_PREFIX:PATH=$PWD/install -DCMAKE_CXX_COMPILER=/glade/u/apps/common/23.08/spack/opt/spack/intel-oneapi-compilers/2023.2.1/compiler/2023.2.1/linux/bin/icpx -DCMAKE_C_COMPILER=/glade/u/apps/common/23.08/spack/opt/spack/intel-oneapi-compilers/2023.2.1/compiler/2023.2.1/linux/bin/icx -DCMAKE_MODULE_LINKER_FLAGS="-lstdc++exp" ../

This is the first thing I would try: Set your view size and your png/jpeg writer resolution to the same size, and make that size something simple (like 800x800). I’ve had issues with mesa when trying to render arbitrarily sized images.

Okay. I did what you suggested. I set the view resolution 800x800 and then I set 800x800 in the PNG extractor but still failing with the same error. Here is my script for your reference,

That’s all I had, sorry. I don’t see anything obviously wrong with your script. Maybe try removing all the opacity stuff?

5

Thanks for your help. I’ll try your suggestion related to the opacity. I am also creating the Catalyst script in my Mac laptop and copying over to the HPC platform which is Linux. I wonder if I need to use same installation (version and OS) to create Catalyst script?

6

You need version numbers to be aligned between the ParaView you used to create the script and the ParaView you use to run, but the build type won’t matter. It’s not even a absolute need. If the versions are not the same, your runtime ParaView might tell you it doesn’t know what this filter option is and throw a Python error (which is not the issue you are seeing), but it’s unlikely to cause a weird crash.

Edit: removed comment about MPI

Okay. I tried to compile paraview super build with debug and partly succeeded. I have following trace,

It show some information coming from libvtkIceTCore-pv. Does this helpful to find out the issue? I’ll try to get full trace but I am not sure I could do it or not. I am also trying to build with OpenGL but since system does not have some core libraries, it could take time for me.

Okay. Definitely there is an issue in the installation. I tried with Python script in the following link,
14. Python & Batch: pvpython and pvbatch — ParaView Documentation 5.12.0 documentation

to test the installation and it is giving same error.

I also run the same command with --verbose=9 and last part of the output is something like following,
