Computer scientists and applied mathematicians searched for 1 quadrillion “triangles” — think three-way connections between friends of friends on a social network — using 1 million processors on LLNL’s IBM BlueGene/Q Sequoia supercomputer. The work is the largest high-performance computing triangle-counting effort to date and earned the team a third consecutive title of “Champions” at the IEEE HPEC Graph Challenge.

Besides broad usage in the tech industry, graph analytics also have national security applications, where algorithms dig through massive datasets to find anomalies or patterns of nefarious activity. It’s in that vein that an LLNL team of computer scientists and applied mathematicians, including Roger Pearce, Geoffrey Sanders, postdoc Benjamin Priest and visiting scholar Trevor Steil, searched for 1 quadrillion “triangles” — relationships such as three-way connections between friends of friends on a social network — using 1 million processors on LLNL’s IBM BlueGene/Q Sequoia supercomputer.
