IBM’s Blue Gene/L supercomputer is once again the fastest computer in the world, a record it has held for the past four years.

World’s Fastest Computer

The official TOP 500 Supercomputers list, released Nov. 12, reports the machine is now three times faster than its competitors with 478 trillion calculations per second, or 478 “teraflops.” The Blue Gene/L is housed at Lawrence Livermore National Laboratory in California. IBM has a record 232 supercomputers on the TOP 500 list, the vast majority built with commodity style, PC microprocessors. The computer maker also outlined its plans to next year achieve a computing milestone known as a “petaflop” – the ability to process 1,000 trillion calculations per second.
