Low remote GPU Utilization with vtk.web

Web
1

Hi.
I’m loading a dicom dataset with vtk pipeline and volume rendering it and vtk.web protocols on a remote system. And accessing that on a different machine. I see that the GPU utilization is very low on the remote system only 3-4% when I interact with the data. But at the same time, local gpu is getting used around 10%. How can I resolve this to use fully only the remote server gpu and not the local system gpu, even if gpu exists locally.

Note:
Remote GPU: Nvidia Quadro 4000
Local GPU: Nvidia GeForce GTX 1650
Dataset Size: 200mb
Mapper: vtkGPUVolumeRayCastMapper
Web protocols used: vtkWebMouseHandler, vtkWebViewPort, and override vtkWebPublishImageDelivery like in this example - web-project-templates/vtkw-server.py at master · Kitware/web-project-templates · GitHub

My guess is that the local GPU is used not for 3d rendering but just to handle the image update on the screen. For the remote, you need more concurrent users or bigger data to render :wink:

Okay thanks.
