Just as a quick comment. One thing I have wondered about for doing cluster support was the possibility of roping in a scripting language to do all scene graph modifications and distribute these scripts to the nodes. I really don't know how viable this idea is yet, having never tried it, or ever
There is actually an cluster implementation of osg, im not sure if its updated lately, but its using MPI for communication.
and I know it distributes changes in the scenegraph, such as transforms, materials transparently...
Its called osgVR

explicit clustering, but now with Quad DualCore, multiGPU machines, who
needs clustering?
Who doesn't have it? ;-)

Thanks, Anders, I forgot about osgVR .
But to answer:
who needs clustering?
Those who want more than 8 display devices. :)

Hello,
I would like to ask the resident OSG gurus about a clustering solution
for OSG. We are attempting to build a new application for VR therapy
purposes on OSG, however there is a constraint that it has to run on
three different kinds of systems -

Hi Jan,
First, let me assure you that clustering _is_ perfectly possible with
OSG. I've developed several simulators that use clustering for
multi-display rendering all based on OSG. That being said, there
is no specific built-in support for clustering in either Producer or
OSG.
We've talked

These trade-offs are quite application dependent. For a flight simulator,

The system should run in a CAVE where the clustering could be required(could - I am not familiar with their system yet). The problems thenwill be how to synchronize the movement of vehicles/insurgents orprojectile trajectories between the machines.
