U.S. Is Once Again Home to the Most Powerful Supercomputer

Rejoice, American processing power fiends: The United States is home to the world's most powerful supercomputer for the first time in three years.

Sequoia, an IBM-designed supercomputer housed at the Lawrence Livermore National Laboratory, hit processing speeds of 16.32 petaflops, blazing past the previous record of 10.5 petaflops set last year by Japan's K Computer.

Used by the U.S. Department of Energy, Sequoia is a highly power efficient BlueGene/Q system running 1,572,864 core processors.

It puts the dual- or quad-core processors found in most common computers to shame, as the average higher-end laptop can achieve speeds of around 100 gigaflops -- about 1,000,000 times slo…
