Embodiments of the invention provide devices and techniques for partitioning a spatial index. In one embodiment of the invention, an image processing system may partition a spatial index into a plurality of portions such that different processing elements may be responsible for traversing a ray through different portions of the spatial index. The determination of where to partition the spatial index may be made based on any number of factors. For example, according to some embodiments of the invention, the spatial index may be partitioned to evenly distribute workload (e.g., determined by real-time performance metrics) amongst multiple processing elements. Partitioning of the spatial index to distribute workload may be based on the total number of nodes, the number of leaf nodes or the number of primitives which will be included in each resulting partition.
