Tracing — Ray 1.12.0
https://docs.ray.io/en/latest/ray-observability/ray-tracing.html
Tracing — Ray 1.12.0 Tracing To help debug and monitor Ray applications, Ray integrates with OpenTelemetry to make it easy to export traces to external tracing stacks such as Jaeger. Note Tracing is currently an experimental feature and under active development. APIs are subject to change. Getting Started First, install OpenTelemetry.

Ray Tracing Fundamentals. Ray casting is the process in a ray tracing algorithm that shoots one or more rays from the camera (eye position) through each pixel in an image plane, and then tests to see if the rays intersect any primitives (triangles) in the scene. If a ray passing through a pixel and out into the 3D scene hits a primitive, then the distance along the ray from the origin …
Ray Packet Tracing with Acceleration using AVX
https://escholarship.org/uc/item/5311b662
Since many rays are traced, the use of single instruction multiple data, or SIMD, instructions (such as the 4-wide SSE) to trace multiple rays simultaneously have been used. However, the incoherence of secondary rays, especially reflection and refraction rays, results in low utilization of the SIMD instructions’ full width.
Large Ray Packets for Real-time Whitted Ray Tracing
https://cseweb.ucsd.edu/~ravir/whitted.pdf
Ray packet tracing has proven very successful for primary visi- bility where neighboring rays are known to be regularly distributed and perspective parallel (ie. all rays meet at a point). Some success has also been demonstrated for point-light shadow rays, but there is verylittlepublishedworkonapplyinglargeraypacketstootherray traced effects.

In this paper, we explore large ray packet algorithms for acceleration structure traversal and frustum culling in the context of Whitted ray tracing, and examine how these methods respond to varying ray packet size, scene complexity, and ray recursion complexity. We offer a new algorithm for acceleration structure traversal which is robust to degrading …
Solved: Re: Ray packets performance - Intel Communities

From your description it seems the rays inside the packet could have enough coherence so that ray packet traversal (rtcIntersect4/8/16) would provide a benefit. The rays inside the packet do not have to share a common origin. Just give it a try and simply use a N times shorter loop. Also you can saf...
