Lawrence Livermore tops Graph 500

New Orleans, Louisiana. Nov. 18, 2014 -- Lawrence Livermore National Laboratory scientists’ search for new ways to solve large complex national security problems led to the top ranking on Graph 500 and new techniques for solving large graph problems on small high performance computing (HPC) systems, all the way down to a single server. "To fulfill our missions in national security and...

Sequoia retains top ranking on Graph 500 for third year running

LLNL's 20 petaflops Sequoia supercomputer again retained its No. 1 ranking on the Graph 500 list, a measure of a system's ability to conduct analytic calculations -- finding the proverbial needle in the haystack. An IBM Blue Gene Q system,Sequoia was able to traverse 15,363 giga edges per second on a scale of 40 graph (a graph with 2^40 vertices). The new Graph 500 list was announced at...
