Web3MPI-only BFS Algorithm and Analysis In this section we ﬁrst introduce an MPI-only BFS algo-rithm in the Graph 500 benchmark, then perform some experimental analyses to identify bottlenecks. 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 The benchmark used in Graph500 stresses the communication subsystem of the system, instead of counting double precision floating-point. It is based on a breadth-first search in a large undirected graph (a model of Kronecker graph with average degree of 16). There are three computation kernels in the benchmark: the first kernel is to generate the graph and compress it into sparse structures CSR or CSC (Compressed Sparse Row/Column); the second kernel doe… fisherman\u0027s friends original members
