- Graph500 abstract "The Graph500 is a rating of supercomputer systems, focused on Data intensive loads. The project was announced on International Supercomputing Conference in June 2010. The first list was published at the ACM/IEEE Supercomputing Conference in November 2010. New versions of the list are published twice a year. The main performance metric used to rank the supercomputers is GTEPS (10^9 Traversed edges per second).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 (model of Kronecker graph with average degree of 16). There are two 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 does a parallel BFS search of some random vertices (64 search iterations per run). Six possible sizes (Scales) of graph are defined: toy (2^26 vertices; 17 GB of RAM), mini (2^29; 137 GB), small (2^32; 1,1 TB), medium (2^36; 17,6 TB), large (2^39; 140 TB), huge (2^42; 1.1 PB of RAM).The reference implementation of the benchmark contains several versions: serial high-level in GNU Octave serial low-level in C parallel C version with usage of OpenMP two versions for Cray-XMT basic MPI version (with MPI-1 functions) optimized MPI version (with MPI-2 one-sided communications)Richard Murphy from Sandia, says that "The Graph500's goal is to promote awareness of complex data problems", instead of focusing on computer benchmarks like HPL, which Top500 is based on.Despite its name, there were only 90 systems in June 2012, not 500. As of November 2012, list has grown up to 124 systems.There is also unofficial list Green Graph 500, which uses same performance metric, but sorts list according to performance per Watt, like Green 500 works with Top500 (HPL).".
