The Roadrunner is a hybrid machine, the world's first, that uses both traditional computer chips and the Cell Broadband Engine which was designed for the PS3. It occupies 6,000 square feet, weighs 500,000 lbs and delivers world-leading efficiency - 376 million calculations per watt. Roadrunner will be used primarily to ensure the safety and reliability of the U.S. nuclear weapons stockpile (we're all gonna die!). It will also do research into astronomy, energy, human genome science and climate change.
In total, Roadrunner connects 6,948 dual-core AMD Opteron® chips (on IBM Model LS21 blade servers) as well as 12,960 Cell engines (on IBM Model QS22 blade servers). The Roadrunner system has 80 terabytes of memory, and is housed in 288 refrigerator-sized, IBM BladeCenter® racks occupying 6,000 square feet. Its 10,000 connections - both Infiniband and Gigabit Ethernet -- require 57 miles of fiber optic cable. Roadrunner weighs 500,000 lbs. Companies that contributed components and technology include; Emcore, Flextronics, Mellanox and Voltaire.
