TITLE: An NSA Big Graph Experiment - slides

ABSTRACT:
Developing scalable graph algorithms in the Big Data era is an imposing challenge. Graph algorithms can be especially difficult to scale because of highly skewed data distribution and irregular data access patterns. Graphs at Big Data scales can exceed the physical memory of even the largest supercomputers which inhibit conventional algorithm implementations. Cloud technologies like Accumulo and MapReduce are promising for Big Graphs but require careful algorithm design to be effective. We present an experiment using Accumulo and MapReduce for Breadth-First Search (BFS) on the largest problem sizes in the Graph500.org industry benchmark.
