IBM Roadrunner is a supercomputer built by IBM at the Los Alamos National Laboratory in New Mexico, USA. Currently the world's seventh fastest computer, it is designed for a peak performance of 1.7 petaflops!. This Supercomputer uses RedHat Enterprise Linux as the operating system.
Roadrunner differs from many usual supercomputers in that it is a hybrid system. Usually supercomputers only use one, since such a design is easier to design and program for. The hybrid design consists of dual-core Opteron server processors manufactured by AMD using the standard AMD64 architecture. Attached to each Opteron core is a PowerXCell 8i processor manufactured by IBM using Power Architecture and Cell technology. As a supercomputer, the Roadrunner is considered an Opteron cluster with Cell 8i accelerators, as each node consists of a Cell attached to an Opteron core and the Opterons to each other.
