Hi All, I'm looking for feedback from users who have worked on clusters that implement some forms of swap ready synchronization. In particular I'm looking at any hooks into osgViewer to allow users to implement their own swap ready implementation, also a software based swap ready could possibly be implemented as part of the core OSG as well.
The hook to adding a swap ready barrier into the view would look something like: viewer.setSwapReadyOperation(myCustomSwapReadyOperation); Something like complicates the mater is that viewer on each slave of the cluster might have more than one graphics context that its rendering too, so in this case we'll have multiple graphics threads per slave, in which case these threads will need to join a barrier that treats each context like a separate machine or the barrier does a local synchronization of the threads on a machine before joining the cluster swap ready barrier. I want to come up with a scheme that supports both ways above, but really need a bit more feedback on what goes into users own swap ready codes, i.e. what would your MyCustomSwapReadyOperation look like, i.e. what does it look right now, this will help me better understand how the most appropriate integration into osgViewer could be done. Robert.
