Graph analytics is gaining traction in the world of big data and IoT. From solving real-world problems such as detecting cyberattacks and creating value from IoT sensor data to precisely identifying drug interactions faster than ever before, graph ... [ Read More ]

How the Cray Graph Engine Manages Graph Databases


In part 1 of this series, we looked at why graph databases are worth considering. In summary, graph databases can answer complex questions that relational databases can’t. In this installment, we will look at how the Cray graph engine represents ... [ Read More ]

Getting Warp Speed for I/O


The humorous statement by computer engineer Ken Batcher that "a supercomputer is a device for turning compute-bound problems into I/O-bound problems" is becoming more genuine, since I/O subsystems are typically slow compared to others parts of a ... [ Read More ]

Graph Databases 101


Let’s talk about graph databases. Some industry watchers claim that they are the fastest-growing type of database. If so, maybe it’s useful to know more about them. Starting with the basics: What is a graph database, and what is it useful ... [ Read More ]
