Dear ParaView user community,
I am having seg fault problem when loading large dataset, >2GB containing 50M grid cells distributed over many vtu files, using GPU local rendering. Strangely, cpu local rendering with Mesa of the same file does not give the seg fault. Smaller dataset also works on local GPU rendering. Since my system has plenty of RAM remains, 1TB in total, out-of-memory is unlikely. OpenGL version reported by Paraview is 4.5 (core profile) Mesa 23.1.4, and 3.2.0 NVIDIA 535.54.03. The output of vglrun glxinfo | grep -i opengl gives me “OpenGL core profile version string: 4.3.0 NVIDIA 535.54.03”. Do you think the seg fault is caused by OpenGL version/driver? Is there any other reason?
A bit of context: the vtu files were generated by sparta/tools/paraview/grid2paraview_cells.py at 4Sep2024 · sparta/sparta · GitHub. I am on Red Hat 7.
