A China-based supercomputer has leapfrogged rivals to be named the world's most powerful system.
A China-based supercomputer has leapfrogged rivals to be named the world's most powerful system.
Tianhe-2, developed by the government-run National University of Defence Technology, topped the latest list of the fastest 500 supercomputers, by a team of international researchers.
Unique features
According to the Linpack benchmark, Tianhe-2 - meaning Milky Way-2 - operates at 33.86 petaflop/sec, the equivalent of 33,860 trillion calculations per second.
The benchmark measures real-world performance - but in theory the machine can boost that to a "peak performance" of 54.9 petaflop/sec.
The project was sponsored by the Chinese government's 863 High Technology Programme - an effort to make the country's hi-tech industries more competitive and less dependent on overseas rivals.
