You could possibly run the application and VirtualGL on Machine C and display the output to Machine A via the VGL Transport or TurboVNC but then set VGL_DISPLAY on Machine C to the X display of Machine B, e.g.:
machine_a> vglconnect machine_c machine_c> export VGL_DISPLAY=machine_b:0.0 machine_c> vglrun my_application or machine_a> ssh machine_c machine_c> /opt/TurboVNC/bin/vncserver machine_a> /opt/TurboVNC/bin/vncviewer machine_c:1 machine_c (in VNC session)> export VGL_DISPLAY=machine_b:0.0 machine_c (in VNC session)> vglrun my_application The security issues with this are numerous. You would have to enable X11 TCP connections on machine_b and then open up machine_b's X server to machine_c using xhost or create an xauth key that can shared to all users of machine_c. Also, this method will use an indirect OpenGL connection between machine_c and machine_b to do the rendering, which isn't really what VirtualGL was designed to do (it will complain about this.) The only reason why it might work OK is that the two machines are connected with IB. You may also run into issues of mismatched OpenGL client and server libraries. machine_c presumably has Mesa installed, whereas machine_b is using NVIDIA's OpenGL implementation. I don't know whether VirtualGL will like having to pull OpenGL functions from Mesa (this hasn't been tested), and I don't know whether Mesa will be able to communicate properly over the network to the NVIDIA libraries to do things like creating Pbuffers. Let me know if it works. On 6/18/10 12:27 PM, Nate Fuhriman wrote: > I have a the following weird situation.
