Thanks Ken, 'Tis as I expected. Nobody replies with "yes it works, it's easy". I want to create a workstation with 3 stereo screens for left/ahead/right for a slightly 'immersivc' effect, and if possible want it to work on windows so that I can continue using visual studio for development. I'll keep looking around, but if anyone has any informaiton, please do chime in. JB As you have guessed, we have run pvserver on nodes with quad cores and dual GPUs under Linux and got it working fine. I don't think many people use windows boxes for pvserver nodes (and I would personally discourage it in general), so you might be on your own here. Is it possible to have one process create a window that spans the display of both graphics cards and have the rest render offscreen?I don't see the WGL_NV_gpu_affinity extension in the OpenGL extensions registry, so it will probably be a while before it becomes available in vtkgl/vtkOpenGLExtensionManager. That's another stumbling block. Sorry I don't have anything more constructive. -Ken On 9/26/08 8:10 AM, "John Biddiscombe" <[EMAIL PROTECTED]> wrote:On linux, an X server will provide display:0, display:1 for two graphics cards on a single node. This works fine. Can the same thing be done on windows in a reasonably straightforward manner? I'd like to know if it's possible to have a dual/quad cpu machine with dual graphics cards and use 2 instances of pvserver as I would do under linux. Google tells me that this extension WGL_NV_gpu_affinity exists, but I would expect we'd need to muck about inside vtkWin32OpenGlRenderWindow and/or related classes to make this work. Has anyone any experience of this or similar technologies that would make the job easy/possible. thanks JB -- John Biddiscombe, email:biddisco @ cscs.ch http://www.cscs.ch/ CSCS, Swiss National Supercomputing Centre | Tel: +41 (91) 610.82.07 Via Cantonale, 6928 Manno, Switzerland | Fax: +41 (91) 610.82.82 _______________________________________________ ParaView mailing list ParaView@paraview.org http://www.paraview.org/mailman/listinfo/paraview -- John Biddiscombe, email:biddisco @ cscs.ch http://www.cscs.ch/ CSCS, Swiss National Supercomputing Centre | Tel: +41 (91) 610.82.07 Via Cantonale, 6928 Manno, Switzerland | Fax: +41 (91) 610.82.82 |
