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.[2][3]
In November 2008, it reached a top performance of 1.456 petaFLOPS, retaining its top spot in the TOP500 list.[4] 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.[5] Roadrunner was decommissioned by Los Alamos on March 31, 2013.[6] In its place, Los Alamos commissioned a supercomputer called Cielo, which was installed in 2010.
