The Asynchronous Job System is a concurrent processing framework that manages parallel task execution through Job Workers, using std::atomic and std::mutex for thread synchronization. It efficiently distributes workloads across multiple threads while maintaining thread safety.
At the heart of a job system are three key elements:
Jobs are individual tasks waiting to be executed. Think of these as work packages - each job represents a specific piece of work that needs to be done, like updating physics, processing AI, or loading assets.
Job Workers are the workhorses of the system. Each worker is a thread that actively looks for jobs to execute. They operate independently, allowing true parallel processing.
Job System acts as the orchestrator, managing the flow of jobs to workers. It maintains queues of jobs in different states (new, executing, completed) and ensures thread-safe operation through synchronization mechanisms.
