Roadrunner was a supercomputer built by IBM for the Los Alamos National Laboratory in New Mexico, USA. The US$100-million Roadrunner was designed for a peak performance of 1.7 petaflops. It achieved 1.026 petaflops on May 25, 2008 to become the world's first TOP500 Linpack sustained 1.0 petaflops system.
In November 2008, it reached a top performance of 1.456 petaflops, retaining its top spot in the TOP500 list. It was also the fourth-most energy-efficient supercomputer in the world on the Supermicro Green500 list, with an operational rate of 444.94 megaflops per watt of power used. The hybrid Roadrunner design was then reused for several other energy efficient supercomputers. Roadrunner was decommissioned by Los Alamos on March 31, 2013. In its place, Los Alamos uses a supercomputer called Cielo, which was installed in 2010. Cielo is smaller and more energy efficient than Roadrunner, and cost $54 million.
IBM built the computer for the U.S. Department of Energy's (DOE) National Nuclear Security Administration. It was a hybrid design with 12,960 IBM PowerXCell 8i and 6,480 AMD Opteron dual-core processors in specially designed blade servers connected by Infiniband. The Roadrunner used Red Hat Enterprise Linux along with Fedora as its operating systems and was managed with xCAT distributed computing software. It also used the Open MPI Message Passing Interface implementation.
