Graph500


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.
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 several hundreds of systems in the rating, growing up to 174 in June 2014.
The algorithm and implementation that won the championship is published in the paper titled "Extreme scale breadth-first search on supercomputers".
There is also list Green Graph 500, which uses same performance metric, but sorts list according to performance per Watt, like Green 500 works with TOP500.

Benchmark

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. 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 ; the second kernel does a parallel BFS search of some random vertices ; the third kernel runs a single-source shortest paths computation. Six possible sizes of graph are defined: toy, mini, small, medium, large, and huge.
The reference implementation of the benchmark contains several versions:
The implementation strategy that have won the championship on the Japanese K computer is described in.
