IBM Roadrunner Breaks Petaflop Barrier. World’s Fastest Supercomputer.

FILED UNDER: Uncategorized

IBM’s Roadrunner has just broken the record set by the BluGene/L as the world’s fastest supercomputer. Roadrunner can achieve speeds twice as fast, breaking through the Petaflop barrier.

A Petaflop equals a quadrillion (thousand trillion) floating point operations per second. It is used as a measure of the processing speed of a computer.

Roadrunner can perform 1.026 quadrillion calculations per second.

The supercomputer cost $133 million to build and uses 12,960 Cell processors plus a smaller number of Opteron processors from AMD.

The Cell processors were originally designed in a joint venture between IBM, Sony and Toshiba and can be found in the PlayStation 3.

Roadrunner runs on Linux and will be used by the U.S. Department of Energy at their Los Alamos National Laboratory for national security problems, long-term climate change predictions and nuclear weapons testing.
