Algorithm 1 describes the MPI-only parallel BFS algorithm. First we partition the graph among the pro-cesses. Let each process own N/p vertices and all the 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 diagonals that bisect opposite angles
