It should be noted that the surge in Chinese systems was achieved with the help of number of generically named Internet service providers and a number of anonymous commercial firms that ran Linpack on their in-house clusters. It’s likely that a good number of these systems don’t actually run what would be considered HPC workloads during their day jobs, so their presence on the list has probably inflated China’s representation to some degree. For what it’s worth though, the US and other countries also claim a number of these questionable HPC machines, so it’s difficult to make objective comparisons. http://www.top500.org/news/china ... nding-us-supremacy/
"It stands to reason that the Sunway TahuLight machine will be ranked number one on the Top 500 list until the “Summit” system built by IBM, Nvidia, and Mellanox Technologies for the US Department of Energy’s Oak Ridge National Laboratory comes online in late 2017 if all goes well, perhaps with around 150 petaflops of peak performance across its 3,500 nodes. The Summit machine will be comprised of multiple 24-core Power9 processors, an unknown number of “Volta” GV100 Tesla coprocessors, and a 200 Gb/sec HDR InfiniBand interconnect."
