China’s Dark Horse Supercomputing Chip: FeiTeng

HPC Wire (01/19/12) Michael Feldman

Chinese researchers at the National University of Defense Technology (NUDT) are developing the FeiTeng processor, an architecture that could launch Chinese supercomputing past the exascale barrier.  FeiTeng was specifically designed for high-performance computing (HPC) and its original version delivered a peak performance of 16 gigaflops, consuming just 8.6 watts of power, which would yield an energy efficiency of about 1.8 gigaflops per watt.  The NUDT researchers also developed a programming language called SF95, which extended FORTRAN95 with 10 compiler directives to utilize the architecture.  China wants to develop and use domestic microprocessors for its HPC industry, and it is likely that the FeiTeng processors will replace both Intel and NVIDIA chips in a future NUDT supercomputer.  China’s currently most powerful machine, Tianhe-1A, is powered by Intel Xeon and NVIDIA Tesla chips.
