1. A Method, comprising: determining whether a plurality of threads in a parallel processing architecture are to execute node traversal or primitive intersection; executing the node traversal or the primitive intersection, based on the determination; determining a first number of the threads that are to execute the node traversal and a second number of the threads that are to execute the primitive intersection; and comparing the first number and the second number; wherein only the node traversal is executed utilizing each of the threads, if the first number is greater than the second number, based on the comparison.
