I need to render a large scale data, so I need to use two GPUs, but I found that one of the GPUs is not used, and the frame rate is very low when only using one GPU. Is there a way to use two GPUs together?

When I was reading the 9.0 release-note, I found that the Nvidia Index plugin might be effective. I haven’t found a way to use it in Paraview, so I’m here to ask for help. Hope someone can help me!

> Hi, I am expecting to take delivery of a small cluster of nvidia GPU enable nodes (each fully capable as machine with keyboard and mouse etc) I am wondering if there is a mode or way of using Paraview so that I can divide up a display on one machine and get the OpenGL rendering done on 4 of the machines? Is this something which requires specialist knowledge or hardware ? Or is that fairly common and built into Paraview ? Where can I start reading up on such parallel OpenGL/GPU usage ? Cheer…
