This talk covers the evolution of REDengine 4's thread-based job system: its API, internal implementation details, and our overall efforts to achieve greater parallelism. The final design was the result of many iterations and stages of feedback while the game was under development. The final approach chosen resulted in nearly all engine and gameplay systems taking advantage of multiple cores, which helped toward reaching our performance goals. Particular topics include solutions for a thread-based approach using counters for interjob dependencies, debugging and profiling, practical philosophy towards CPU resource sharing, integration with other systems, and overall approaches to the composability of jobs.
Attendees will learn about the challenges and implementation details in Cyberpunk 2077 of a thread-based job system using counters for dependencies, as well as the various approaches to encourage programmers to better parallelize their own systems and the challenges they may face in doing so.
The intended audience is programmers and developers who have an interest in job systems or multithreading and are looking to explore various approaches. Deep knowledge of the topic isn't required, but familiarity with multithreading concepts is recommended.
