In the previous post I described my issues with a component-based entity system I used when working on ICE. The most important of these was probably the inability to split the entity system into multiple threads.
Tharsis is my attempt to design an entity component framework without these limitations. Tharsis is a stand-alone project, not tied to any single game. Its main goals are:
- Simulation results should be independent of how the processes (Tharsis’ equivalent for systems in entity frameworks such as Artemis) are ordered.
- Processes shoule be automatically assigned to separate threads (mostly) without explicit thread management by the programmer.
- Performance should scale with increasing amount of cores (as long there is a large enough number of processes).
- Efficient memory organization, keeping CPU cache in mind.
- Open source with liberal (Boost) licencing.
I hope to write a series of posts describing Tharsis and its development as I add new features. Meanwhile, if you need a D component entity system right now, check out ArtemisD.
