摘要： An apparatus and method for compressing ray tracing data prior to transmission between nodes. For example, one embodiment of an apparatus comprises: a first node comprising a first ray tracing engine, the first node communicatively coupled to a second node comprising a second ray tracing engine; first compression circuitry coupled to the first ray tracing engine, the first compression circuitry to perform compression on ray tracing data of the first ray tracing engine to produce a first compressed stream of ray tracing data; and interface circuitry to transmit the first compressed stream of ray tracing data from the first node to the second node.

摘要： While prefetching data for a second fiber, a hierarchical data structure is traversed using a first fiber after deferring traversal for the second fiber. Then context is switched to the second fiber, and the hierarchical data structure is traversed using second fiber while prefetching data for another fiber.
