HPC Roadrunner

Roadrunner, world's first petaflop/s system, remains #1 on the Top500 and #7 on the Green500

• The 32nd edition of the list of the world’s TOP500 supercomputers was released on November 14, with the 1.105 petaflop/s Roadrunner system holding on to the top spot it first achieved in June 2008. Seven of the top 10 systems on the newest TOP500 list are located at DOE facilities. Nine of the top 10 supercomputers are located in the United States. The most powerful system outside the U.S. is the Chinese-built Dawning 5000A at the Shanghai Supercomputer Center. It is the largest system which can be operated with Windows HPC 2008 operating system.

• Green500 ranks the world's top supercomputers by energy efficiency. On the November Green500 release, Roadrunner is #7. Roadrunner is cited for "extraordinary energy efficiency... For comparison, the last two supercomputers to top the TOP500 are #43 and #499 on the Green500." (July 1, 2008)

Roadrunner Background

In a test run on May 27, the Roadrunner supercomputer, built by IBM with funding from the National Nuclear Security Administration (NNSA) for Los Alamos National Laboratory, achieved a long-sought supercomputing goal: performing more than a thousand trillion operations per second, or petaflop/s.

A “flops” is an acronym meaning floating-point operations per second.  One petaflop/s is 1,000 trillion operations per second.  To put this into perspective, if each of the 6 billion people on earth had a hand calculator and worked together on a calculation 24 hours per day, 365 days a year, it would take 46 years to do what Roadrunner would do in one day.

Roadrunner is the first supercomputer to use a hybrid processor architecture, which is based on both Opteron X64 processors from Advanced Micro Devices (AMD) and the IBM Cell Broadband Engine™ (Cell BE) processing elements.

Roadrunner will be housed at NNSA’s Los Alamos National Laboratory. The laboratory worked collaboratively with IBM, the manufacturer, for six years to deliver a novel computer architecture that can meet the nation’s evolving national security needs.  The result has redefined the frontier of supercomputing, not only by crossing the one petaflop threshold, but also by introducing a new paradigm for the future.

Roadrunner is also rated as very energy efficient (green) (performance/watt).
