New GPU Tracking Algorithm: Wavefront Path Tracing
https://weekly-geekly.imtqy.com/articles/461017/
Wavefront path tracing, as it is called Lane, Karras and Aila from NVIDIA, or streaming path tracing, as it was originally called in Van Antwerp ’s master's thesis, plays a crucial role in developing efficient path tracers on the GPU, and potentially path tracers on the CPU. However, it is quite counterintuitive, therefore, to understand it ...
Megakernels Considered Harmful: Wavefront Path …

4.2 Wavefront Formulation Our wavefront path tracer formulation is based on keeping a pool of 1M (= 220) paths alive at all times. On each iteration, every path is advanced by one segment, and if a path is terminated, it is regenerated during the same iteration.

Our solution is a wavefront path tracer that keeps a large pool of paths alive at all times, which allows executing the ray casts and the material evaluations in coherent chunks over large sets of rays by splitting the path tracer into multiple specialized kernels.
Distributed Tracing Overview | Tanzu Observability

The Wavefront OpenTracing SDKs let you to choose how to send trace data to Wavefront – through a Wavefront proxy or directly to the Wavefront service. Using a Wavefront proxy is generally recommended. If you have not yet instrumented your code, you can add instrumentation by using Wavefront OpenTracing SDKs or the Wavefront Java Tracing Agent.
