In addition to the low level API in the Enlighten library itself, the Enlighten SDK now includes a high level run time layer built on top of the low level API.
This part of Enlighten is shipped as source code. As well as being available for integration into a game engine, it serves as example usage of the Enlighten low level API. More details are available in the High Level Runtime section of the SDK documentation.

The MultithreadCpuWorker works by putting tasks in a list, and then executing TaskProcessors on several threads in parallel.
A TaskProcessor pulls tasks off the list one by one, until either the whole list is done, or an ILimiter tells it to stop.
The executing threads are accessed through the IThreadGroup interface. If none is supplied then the MultithreadCpuWorker will create a DefaultThreadGroup which executes tasks in serial on the calling thread (ie the update manager worker thread). When it is destroyed, the MultithreadCpuWorker will call Release() on the IThreadGroup interface it was passed. There is an implementation of IThreadGroup which uses Intel Threaded Building Blocks in the TbbThreadGroup.h header (which does not get compiled in to EnlightenHRLT).
ILimiter is an optional interface which can be implemented by the application. A simple FixedTimeLimiter is included here which times out after a given fixed time. Note that the limiter only controls the point at which new tasks can be started, not the total time taken.
The Enlighten update loop consists of three multithreaded phases: input lighting, solve tasks, and probe interpolation. Within each phase tasks can run in parallel (for instance, a probe set can be solved at the same time as a system), but tasks from different phases cannot run together.
If no limiter is supplied, the MultithreadCpuWorker will complete one full pass through the update loop for each call to UpdateRadiosity(). However, it can remembers where in the udpate loop it previously stopped, so if a limiter tells it to stop part-way through an update it will resume from where it left off. This ensures that the Enlighten data remains in a consistent state at all times. Enumeration of Enlighten task types. These are executed by the TaskProcessors.
