Detailed Description

SimulationIslandManagerMt – Multithread capable version of SimulationIslandManager Splits the world up into islands which can be solved in parallel.

In order to solve islands in parallel, an IslandDispatch function must be provided which will dispatch calls to multiple threads. The amount of parallelism that can be achieved depends on the number of islands. If only a single island exists, then no parallelism is possible.
