Simultaneously with the release of the Top 500 list of the world's fastest supercomputers, and the release of the Green 500 list of the most efficient supercomputers, the ranking the best performing data crunching computers was released.
Rather than focusing on floating point performance, the Graph 500 benchmarks supercomputers in kernel disciplines of concurrent search, optimization (single source shortest path), and edge-orientation (maximal independent set).
Lawrence Livermore National Laboratory's Sequoia supercomputer, which is listed second in the Top 500, came out on top in the Graph 500 with a result of 15,363 GTEPS (billion edges traversed per second). Sequoia was nearly 50 percent faster that Argonne National Laboratory's Mira with 10,461 GTEPS, and almost three times faster than Forschungszentrum Juelich's JUQUEEN, which posted 5,848 GTEPS.
The ranking should be taken with a grain of salt, since not all of the world's supercomputers in the Top 500 list are listed in the Graph 500 as well, which makes a direct comparison rather difficult. However, Sequoia is exactly 100 percent faster that Mira in the Top 500 list, but only 46 percent faster in the Graph 500 benchmark.
The Graph 500 team said it is optimizing its benchmarks and will be addressing the graph-related business areas of cybersecurity, medical informatics, data enrichment, social networks, and symbolic networks.
