IBMs Roadrunner Speeds Toward a Petaflop - The Cell-Based QS22

The New Mexico state bird is the roadrunner, which helps explain the name that IBM bestowed upon the supercomputer it plans to install at New Mexico-based Los Alamos National Laboratory in August. The name is also an allusion to the roadrunner's speed: IBM engineers say they believe that the high-performance supercomputer will become the first to break the petaflop mark-


What makes Roadrunner unique is that IBM will use its Cell processor, originally designed for game consoles, as a way to accelerate the more difficult scientific calculations that the supercomputer will perform during its time in Los Alamos. This is the inside of the QS22 blade, which holds the Cell processors. Roadrunner uses two QS22 blades with a total of four cell processors.
