ShenWei SW1600 is the third generation CPU by Jiāngnán Computing Research Lab. Operating at 1.1 GHz, it achieves 140 GFLOPS floating point performance from its 16 cores RISC architecture. The CPU is a national key collaborative laboratory project by Jiāngnán Computing Research Lab and High Performance Server & Storage Technologies. The People's Republic of China asserts its sole intellectual property rights. A little more information about the 65 nm ShenWei SW-3 multi-core CPU project can be found on official web site of High Performance Services & Storage Technologies - national key research laboratory. Some characteristics of the SW1600 core explained:
Sunway BlueLight MPP (神威蓝光) Supercomputer, is the first publicly announced PFLOPS supercomputer using ShenWei processors solely developed by the People's Republic of China. It ranked #2 in the 2011 China HPC Top100, #14 on the November 2011 TOP500 list, and #39 on the November 2011 Green500 List. The machine was installed at National Supercomputing Jǐnán Center (国家超算济南中心) in September 2011 and was developed by National Parallel Computer Engineering Technology Research Center (国家并行计算机工程技术研究中心) and supported by Technology Department (科技部) 863 project. The water-cooled 9-rack system has 8704 ShenWei SW1600 processors (For the Top100 run 8575 CPUs were used, at 975 MHz each) organized as 34 super nodes (each consisting of 256 compute nodes), 150 TB main memory, 2 PB external storage, peak performance of 1.07016 PFLOPS, sustained performance of 795.9 TFLOPS, LINPACK efficiency 74.37%, and total power consumption 1074 kW.
