A new Chinese supercomputer is capable of 54.9 petaflops, more than twice the speed of any system in the world, according to researcher Jack Dongarra, who examined the system (pdf).
The current fastest supercomputer in the world, according to a biannual Top 500 list, is at the Oak Ridge National Laboratory in Tennessee. It runs at nearly 18 petaflops, far short of the new Chinese machine, which reportedly cost 1.7 billion yuan to develop.
Computer World reports:
China’s latest supercomputer, called Tianhe-2 or Milkyway-2, has 32,000 multicore Intel Xeon Ivy Bridge chips, and 48,000 Xeon Phi chips, a co-processor based on Intel’s MIC (Many Integrated Core) architecture.
Each Phi processor is capable of more than teraflop of speed, or one trillion floating point operations per second. A petaflop is 1,000 teraflops, or one quadrillion floating-point operations per second. An exascale system is 1,000 petaflops.
