A system and method for constructing binary radix trees in parallel, which are used for as a building block for constructing secondary trees. A non-transitory computer-readable storage medium having computer-executable instructions for causing a computer system to perform a method is disclosed. The method includes determining a plurality of primitives comprising a total number of primitive nodes that are indexed, wherein the plurality of primitives correspond to leaf nodes of a hierarchical tree. The method includes sorting the plurality of primitives. The method includes building the hierarchical tree in a manner requiring at most a linear amount of temporary storage with respect to the total number of primitive nodes. The method includes building an internal node of the hierarchical tree in parallel with one or more of its ancestor nodes.
