Abstract: A method of operating a graphics processor to perform ray tracing. The graphics processor includes a ray tracing circuit that can be messaged by the graphics processor's programmable execution unit during execution of a program to perform a respective traversal of the at least one ray tracing acceleration data structure to be traversed for that ray. The ray tracing circuit may need to stop a ray's traversal to return the ray's processing to the programmable execution unit before the ray's traversal is subsequently restarted. In that case, the ray's traversal is restarted from the beginning.

Abstract: A computer-implemented method for simulating web traffic to sandbox-test a new digital content platform service or feature. For example, implementations described herein identify and clone live production traffic from a first route including an existing digital content service. The implementation further forks the cloned production traffic along a second route to a new digital content service. By monitoring and correlating production responses from both the first and second routes, the implementations described herein can analyze and compare performance, accuracy, and correctness of the new digital content service to determine whether the new digital content service can handle live production traffic at scale. Various other methods, systems, and computer-readable media are also disclosed.
