OSPRay crash on startup.

ParaView Support
1

I am having OSPRay/ possible VisRTD crashes on a new workstation. This is Linux. ParaView 5.9.0, paraview.org download. Crashes on initial startup.

This issue does disappear when using the disable Catalyst and VisRTD environment variables.

Would it be possible to enable OSPRay/ VisRTD when used, rather than initial startup?

Dave, email me directly if you want more specific information on this machine.

Thanks,

Alan

Were you using the following

$ export VTK_DISABLE_VISRTX=1
$ export VTK_DISABLE_OSPRAY=1

Or the one in the doc? Those needs to be fixed. @vbolea

Yep, the environmental variable list in the docs was outdated, it was recently updated in master, unfortunately it did not come with the 5.9 release.

I think that Alan was not referring about the env vars not working rather than only initialize those backend when we use them, not when we start ParaView.

I spent sometime in that part of VTK, IMO lazy initialization sounds like a good solution for this, we can survey to see if its possible.

Vicente, you are correct. The environment vars work as advertised. BEFORE setting the environment vars, ParaView should not crash on startup.

Yes Alan, please do pass along more info to help me diagnose. It would also help to know if 5.8.x starts up and if enabling ray tracing works there. Furthermore it would be good to see if the nightly build crashes on startup. Ben added a change there to avoid the problem in another way. If that doesn’t work I’ll submit an MR to construct the vtkOSPRayPass on demand as you suggest. It should be as simple as changing the vtkNew in vtkPVRenderView to a smartpointer that is assigned on first use.

Ben’s change is mac specific, so it is unlikely to help, I’ll work on the patch.

I still have this issue on a specific machine: https://gitlab.kitware.com/paraview/paraview-superbuild/-/issues/201
