ParaView

Running the OOD container by hand as it is broken in OOD (end of 2024)

Instructions provided by Orian.

The getEglCard script in the container in use at the end of 2024 provides the wrong GPU device. It sets VGL_DISPLAY to /dev/dri/card0 which does not correspond to what nvidia-smi suggests:

/dev/dri/by-path/pci-0000:48:00.0-card -> ../card1

The solution seems to be to run in a desktop session and then

singularity exec --nv /appl/local/ood/$SLURM_OOD_ENV/container_images/paraview_5.11.sif \
  bash -c 'export VGL_DISPLAY=/dev/dri/card1; vglrun paraview'

Check the "About" dialog in ParaView to confirm that the GPU is being used. It should show a proper OpenGL version and as the OpenGL renderer "NVIDIA A40/PCIe/SSE2".
