Abstract: An apparatus and method are described for utilizing volume proxies. For example, one embodiment of an apparatus comprises: a volume subdivision module to subdivide a volume into a plurality of partitions, the apparatus to process a first of the partitions and to distribute data associated with each of the other partitions to each of a plurality of nodes; a proxy generation module to compute a first proxy for the first partition, the first proxy to be transmitted to the plurality of nodes; and a ray tracing engine to perform one or more traversal/intersection operations for a current ray or group of rays using the first proxy; if the ray or group of rays interacts with the first proxy, then the ray tracing engine to send the ray(s) to a second node associated with the first proxy or retrieves data related to the interaction from the second node.

Abstract: One embodiment provides for a parallel processor comprising a processing array within the parallel processor, the processing array including multiple compute blocks, each compute block including multiple processing clusters configured for parallel operation, wherein each of the multiple compute blocks is independently preemptable. In one embodiment a preemption hint can be generated for source code during compilation to enable a compute unit to determine an efficient point for preemption.

Abstract: An apparatus and method are described for performing a distance test in a ray tracing system. For example, one embodiment of a graphics processing apparatus comprises: a ray tracing traversal/intersection unit to identify two or more ray-surface intersections, each of the ray-surface intersections being assigned a unique hit point identifier (ID); and a distance testing module to disambiguate the order of the ray-surface intersections using the hit point ID if the two or more of the ray-surface intersections share the same distance.
