|Overview:||These days concurrent programming is mandatory for game developers. Use of synchronization primitives is often a solid way to achieve the goal but it has its drawback. This talk presents an innovative way to schedule an engine loop by working around data contention in a multithreaded environment. This data-driven scheduling minimizes data races and maximizes hardware occupation including Cell's SPUs. Implemented using lock-free algorithms, it achieves better performance compared to more traditional schedulers. By the way, did you know that SPU programming can be easy?|
