Problem Description
This benchmark computes the level of each node from a source node in an unweighted graph. It starts at node 0 and explores all the nodes on the same level and move on to nodes at the next depth level.Algorithm
This code has been generated using IrGL compiler. IrGL produces CUDA code and automatically adds a few optimizations to the CUDA code. For more information on the implementation and these optimizations please read this paper.Performance
