Hi Utkarsh,

Thank you for your reply and your explanation. And unfortunately we are looking into possibly using GPU- accelerated algorithm. We will look into getting vtk-m configured in our ParaView.

Thanks

Simon,

The answer depends on whether you want to ParaView to use GPU for rendering alone or also for computation e.g. contours. For former, it's automatic via OpenGL. So long as your environment and/or your build is set up such that ParaView picks up the OpenGL implementation provided by your GPU drivers, you'll get GPU acceleration. For GPU-accelerated algorithms, you have to enable VTK-m support at build time and then enable CUDA support for VTM-m. Currently, you need create special filters via the VTM-m plugin [1] to use accelerated versions of common algorithms like contour. In future, this will be automatic, and you will be able to simply use the generic filters.

Hope that helps.

Utkarsh
