Hi Lizheng,
First up you need to split up the problem into single machine,
multiple CPU/GPU and clustering of machines.
The osgViewer library supports multiple CPU/GPU set ups out of the
box. In fact in you run any of the examples it will be default querry
all the available displays and open up the view across all of them and
automatically run multiple threads/multiple contexts.
Doing SLI/CrossFire relies upon the graphics drivers being set up for
this type of rendering, it isn't really something the OSG can get
involved in.
The OSG doesn't not directly support clustering, there is a very
simple example osgcluster that illustrates how you might use UDP
packets to run a simple viewer across a network. For more complete
solutions you need to look further afield to tools like Equalizer,
Vrjuggler etc.
