Hello, I am not sure if it is a bug but we have an issue:
Our setup is a 2-GPU 'VGL-served' machine. With VGL present, we want: - two offscreen renderers using :0.0 and :0.1 contributing to: - one on-screen renderer rendering and assembling :0.0 and :0.1 using the forwarded DISPLAY (:10.0, redirected to :0.0 by VGL) This setup, when run under VirtualGL, should use the VGL redirect for the on-screen renderer and have no interference on the offscreen renderers. We use Red Hat 6.5 on our server and Ubuntu 14.04 on our client. The GPUs are Geforce GTX 580 with 3GB memory. The last time we tested it, everything was working. But now, it seems that there is some problems. When we launch our openGL application using vglrun, only one GPU is used, even though the offscreen renderers pass :0.0 and :0.1 to XOpenDisplay(). We used nvidia-smi to monitor video memory of each GPU and only one GPU is allocating memory. Has something changed in VirtualGL on how the context creation is handled? Cheers, Grigori PS: Please see http://sourceforge.net/p/virtualgl/mailman/virtualgl-devel/thread/2B770B96-306D-4094-A347-6B651577BBCE%40gmail.com/#msg29184059 for the discussion when we implemented this feature for more background. ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
