ShenWei SW1600 microprocessor
ShenWei SW1600, aka SW-3, 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:
- Four-issue superscalar
- Two integer and two floating-point execution units
- 7-stage integer pipeline and 10-stage floating-point pipeline
- 43-bit virtual address and 40-bit physical address
- Up to 8 TB virtual memory and 1 TB of physical memory supported
- L1 cache: 8 KB instruction cache and 8 KB data cache
- L2 cache: 96 KB
- 128-bit system bus
With the published information, similarity with Alpha 21164A is suggested.[1][unreliable source?]
History of ShenWei processors
The ShenWei series of microprocessors was developed primarily for the use of the military of the People's Republic of China. The original microarchitecture is believed to be inspired by DEC Alpha.[2][unreliable source?]

Sunway BlueLight MPP System
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.[3][4] It ranked #2 in the 2011 China HPC Top100,[5][6] #14 on the November 2011 TOP500 list,[7] and #39 on the November 2011 Green500 List.[8] The machine was installed at National Supercomputing Jǐnán Center (国家超算济南中心) in September 2011[3][4] 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[5]) 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.[5][9]
The Sunway BlueLight is ranked 103rd[10] as of the November 2015 TOP500 list[update] (ranked highest at 14th when it appeared on the list in November 2011; then 65th in the November 2014) and is still the only ShenWei powered supercomputer on the TOP500 list.[11]
