Re: [osg-users] Multi GPU Rendering
I have tested osgViewer on the pc with two GPU card, windows 7 and osg 2.8.3. When I display the statistics, I can see the 2 GPUs. And, If I move the scene from one screen to the other, I can see the load of the GPUs that change. But, I have some problem with the mouse. Sometimes, using the mouse only move the scene on 1 screen and not on the other. And I can only move the scene using the mouse on screen 2 (whereas the main screen is screen 1). -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=42164#42164 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Multi GPU Rendering
I'm sure it can, but effectiveness will depend on what you mean by part. We e.g. use multiple gpu with video streams on multiple monitors. You can also google for equalizer opengl. jp On 18/08/2011 14:37, Miguel Lokida wrote: Hello, I would like to know if OSG can benefit of a PC with several GPU ?

The OSG osgViewer library natively supports multi-threaded multiple graphics context usage, and for you case you can assign each context to a different GPU just be setting the GraphicsContext::Traits appropriately. This type of usage is typically used for multiple screen outputs. From what little you have mentioned it's impossible to say what expectations/intentions you actually have. Do you wish multiple outputs or a single output? Robert. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Multi GPU Rendering
Hello, Thank you for your reply. I have one computer and inside, there's 2 GPU card with. Each GPU cards has 2 video outputs. I would like to use 4 screens (connected to the 2 GPU cards) and divide my camera viewport in 2. Like this, I could see my scene on 4 screens. I think that the firt GPU card would render the half screen and display the result on two screen (dual screen) and the second GPU card would render the last half screen on the two others screens (dual screen). May be my idea is wrong ? I have look at the http://forum.openscenegraph.org/viewtopic.php?t=7323postdays=0postorder=aschighlight=gpu_affinitystart=15 post but I don't know is the problem has been resolved. Moreover concerning Equalizer, I have look at it and try it but unfortunately I have not really managed to do what I wanted and I find the documentation for examples very light and there is less activity than here. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=42126#42126 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

The osgViewer library supports this natively so there won't be any need to worry about Equalizer. The osgViewer library by default will open up windows across all your screens and run multi-threaded, You can also explictly set things up, see the osgcamera example. BTW, what happens when you run osgviewer on your system? Also what OS and hardware are you working with?

Re: [osg-users] Multi GPU Rendering
Hi, For now, I haven't yet tested the multiGPU on the computer. It is a computer using windows 7 and 2 Nvidia GTX 590. The aim would be to use 2 or 3 pc with 2 GPU card in each and display the result on a display wall. I have seen the osgCluster example and it seems to be a good way. The hard part would be to synchronize the animation of the scene on the PC. I have not ever do that.
