This week was updated list of 500 computing systems in the world. Like last time, in the first place came the Chinese supercomputer. Its name Sunway TaihuLight. An established system performance in the Linpack benchmark is 93 petaflops, and reaches a peak of 125 petaflops. The previous "Chinese" Tianhe-2, for example, was based on the Intel Xeon processor and accelerators Xeon Phi.
Sunway SW1600 processors as part of a commercial system debuted in 2014. For the Americans, it was a considerable surprise. At that time, the system of 16-core RISC-based Sunway SW1600 fully develop the Chinese gave out 795 teraflops. The new processors SW26010 consists of 260 processor cores and deliver 3 teraflops processor or 93 petaflops on the system. At the same time energy efficiency solutions is pretty good and the average is 6 gigaflops per watt. For comparison, the newest 14-nm Intel Xeon Phi processors operating with an efficiency of about 12 gigaflops per watt.
By the way who are interested can study published yesterday a report on the University of Tennessee SW26010 processors and system Sunway TaihuLight.
IBM is going on a par with NVIDIA. Announced on the preparations for the launch of 2018 Summit system platform IBM Power9 processors and NVIDIA Volta accelerators. The system will consist of only 3,400 units. The layout of the nodes is not disclosed. Sunway TaihuLight system, for example, consists of 40,960 units of one processor per node.
Summit Each node of the system will contain more than 500 GB of memory combined HBM and DDR4, as well as 800 GB of flash memory caching in the form of non-volatile buffer. System performance promises about twice surpass Sunway TaihuLight performance and reach the mark of 200 petaflops. This year, the number of supercomputers in China for the first time exceeded the number of supercomputers in the United States.
