Webof Graph500, Breadth First Search (BFS), contains a lot of irregular memory accesses. Most of SIMD ISAs do not provide support for indexed memory accesses and this lack has prevented vectorization of BFS. The Xeon Phi is a recent massively parallel x86 micropro-cessor designed by Intel and is based on the Larrabee GPU WebSpMSpV algorithm for solving BFS on distributed systems. To the best of the authors’ knowledge, no equivalent imple-mentation has been made for the GPU. On GPUs, parallel BFS algorithms are challenging be-cause of irregular memory accesses and data dependency between iterations. Harish and Narayanan [4] gave the ﬁrst
