China Surpassing U.S. With 54.9 Petaflop Supercomputer: China has developed a supercomputer capable of 54.9 petaflops, more than twice the speed of any system in the United States, according to University of Tennessee professor Jack Dongarra. China's newest system, which was built with Intel chips but also contains Chinese-produced technologies, would be the world's fastest. Dongarra says the new system, called Tianhe-2, has 32,000 multicore Intel Xeon Ivy Bridge chips and 48,000 Xeon Phi chips. The world's current fastest supercomputer is located at the Oak Ridge National Laboratory and runs at nearly 18 petaflops. However, Dongarra notes that China may have the leading system for some time, as the next large acquisition of a supercomputer for the U.S. Department of Energy will not be until 2015. U.S. researchers recently warned Congress that the United States is at risk of falling behind in high-performance computing development unless it commits hundreds of millions of dollars to exascale research. China wants to produce an exascale system before 2020, while the United States is not expected to produce an exascale system until about 2025, according to industry experts.
