China's latest supercomputer, which may be officially cited as the world's fasted when Top 500 global rankings are released mid-month, is running Chinese- made interconnects and software. China-made CPUs are up next, Beckman said.
Tianhe-2 or Milkyway-2, which will have 3.1 million cores, has a theoretical speed of almost 55 petaflops. It's been tested so far at nearly 31 petaflops. A petaflop is 1,000 teraflops, or one quadrillion floating-point operations per second. An exascale system is 1,000 petaflops.
Beckman, in an interview, explains the significance of China's moves, and the power problem facing the push to exascale.
