SAN FRANCISCO — A Chinese supercomputer has been ranked as the world’s second-fastest machine, surpassing European and Japanese systems and underscoring China’s aggressive commitment to science and technology.

The Dawning Nebulae, based at the National Supercomputing Center in Shenzhen, China, has achieved a sustained computing speed of 1.27 petaflops — the equivalent of one thousand trillion mathematical operations a second — in the latest semiannual ranking of the world’s fastest 500 computers.

The newest ranking was made public on Monday at the International Supercomputer Conference in Hamburg, Germany. Supercomputers are used for scientific and engineering problems as diverse as climate simulation and automotive design.

The Chinese machine is actually now ranked as the world’s fastest in terms of theoretical peak performance, but that is considered a less significant measure than the actual computing speed achieved on a standardized computing test.
