This is really a good situation where OpenCL can have good benefits.
Based on your node system a custom OpenCL source code can be generated
(like the current Material->PixelShaders) and can be performed and
cached. OpenCL has an event system that can be used for joining threads
etc. You should really look into that aspect of OpenCL.
As you could have read am I looking into Node systems as these can
become very complex for normal CPU based things. And your node system
can also have a very large dataset. That is also a very good requirement
for going to OpenCL.
