Roadrunner, [...] one powerful enough to operate at one petaflop (one thousand trillion calculations per second). That’s twice as fast as the current No.1 rated IBM Blue Gene system at Lawrence Livermore National Lab – itself nearly three times faster than the leading contenders on the current TOP 500 list of worldwide supercomputers.
Roadrunner is the world’s first hybrid supercomputer. In a first-of-a-kind design, the Cell Broadband Engine® — originally designed for video game platforms such as the Sony Playstation 3® — will work in conjunction with x86 processors from AMD®.
Made from Commercial Parts. In total, Roadrunner connects 6,562 dual-core AMD Opteron® chips as well as 12,240 Cell chips (on IBM Model QS22 blade servers). The Roadrunner system has 98 terabytes of memory, and is housed in 278 refrigerator-sized, IBM BladeCenter® racks occupying 5,200 square feet. Its 10,000 connections –both Infiniband and Gigabit Ethernet — require 55 miles of fiber optic cable. Roadrunner weighs 500,000 lbs. Companies that contributed components and technology include; Emcore, Flextronics, Mellanox and Voltaire.
