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, using two different processor architectures. Usually supercomputers only use one, since such a design is easier to design and program for. To realise the full potential of Roadrunner, all software will have to be written specially for this hybrid architecture. The hybrid design consists of dual-core Opteron server processors manufactured by AMD using the standard AMD64 architecture.
