The Cray Urika-GD graph discovery appliance is a computer application that finds and analyzes relationships and patterns in the data collected by a supercomputer. Introduced in 2012 by Cray Inc., it was the company's maker's first product to produce meaningful graphs based on large amounts of data, often from multiple sources, and to make useful connections among those data. Many organizations now have vast stores of information like this—called "big data"—that they can analyze and use to improve their operations, products or services.
