  • METHOD FOR FORWARD PROGRESS AND PROGRAMMABLE TIMEOUTS OF TREE TRAVERSAL MECHANISMS IN HARDWARE
    Publication number: 20240169655
    Abstract: In a ray tracer, to prevent any long-running query from hanging the graphics processing unit, a traversal coprocessor provides a preemption mechanism that will allow rays to stop processing or time out early. The example non-limiting implementations described herein provide such a preemption mechanism, including a forward progress guarantee, and additional programmable timeout options that can be time or cycle based. Those programmable options provide a means for quality of service timing guarantees for applications such as virtual reality (VR) that have strict timing requirements.
    Type: Application
