Thanks Ken,<br>

'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.<br>
<br>
I'll keep looking around, but if anyone has any informaiton, please do
chime in.<br>

<pre wrap="">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.

<pre wrap="">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
