China to Build Another 100-Petaflops Hybrid Supercomputer By 2014?

The Chinese Ministry of Science has commissioned a new 100-petaflop supercomputer to be used in space exploration and health care research, according to a VR-Zone report.
China previously acknowledged that it was building the Tianhe-2, a successor to the Tianhe-1a supercomputer, with the goal of reaching 100 petaflops of peak performance by 2015. However, the new report indicates that China has pushed up its goal of achieving 100-petaflop performance by a year. The new system reportedly will consist of about 100,000 Intel Ivy Bridge-EP Xeon E5-2600 v2 processors and about 100,000 next-generation Knights Landing Xeon Phi multicore x86 coprocessors.
The current Knights Corner Xeon Phi coprocessors have 60 active cores running at 1.05 GHz delivering slightly more than one teraflops of power. The Knights Corner chips are etched in 22-nanometer processes, so Knights Landing must either use the same process and have architectural improvements or utilize a new process to implement a shrink and a core count boost. With 100,000 Xeon Phi v2 coprocessors, the new system could reach about 135 petaflops.
