Meet the brand new international’s fastest supercomputer

China has executed it once more — besides this time with a modern day supercomputer. The Sunway TaihuLight is now the quickest gadget inside the world, in keeping with the twice-according to-year TOP500 listing, with a lovely Linpack benchmark result of ninety three petaflops. That makes it 3 times faster than the earlier champion, China’s Tianhe-2, which we’ve protected numerous times on ExtremeTech and had sat on pinnacle of the listing because it first went on-line in 2013.
What’s even more interesting this time around is what’s beneath TaihuLight’s hood: a regionally evolved ShenWei processor and custom interconnect, instead of parts sourced some other place. The ShenWei 26010 is a 260-core, sixty four-bit RISC chip that exceeds 3 teraflops at most tilt, placing it on par with Intel’s Knight’s touchdown Xeo Phi. TaihuLight carries forty,960 ShenWei 26010s, one for each node that also carries 32GB of RAM, including as much as a complete of over 10 million cores.
As HPCwire illustrates, each SW26010 processor chip has 4 predominant additives:
which are grouped collectively in this simple layout of a node:
The chip has 4 center companies, every with 64 factors and a unmarried control processing detail, for a complete of 65 in step with organization (to get to the 260 center general). each organization sports a 136.5 GB/sec memory controller; there’s no word on the manner technology node used to fabricate the chip. The TOP500 document said that the chip also lacks any traditional L1-L2-L3 cache, and rather has 12KB of coaching cache and 64KB “neighborhood scratchpad” that works type of like an L1 cache.
The custom interconnect, known as the Sunway network, is based totally on PCIe and can provide 16 GB/sec of top bandwidth among nodes, with 1ms latency.
TaihuLight could be used for climate, weather, and earth structures modeling; existence science studies; manufacturing; and records analytics, consistent with TOP500’s respectable document. The system is positioned on the countrywide Supercomputing center in Wuxi, which sits about two hours west of Shanghai.
this is the first time China has the maximum systems on the listing, with 167, rather than the us, which is all the way down to 165. China additionally now has the pinnacle  fastest structures as well. Europe has one zero five structures, down two from November 2015. Cray maintains to lead in total overall performance proportion at 19.9 percentage, but that’s down from 25%. China’s countrywide studies center of Parallel Computing Engineering & technology, which developed TaihuLight, takes the second one spot right here with this single device, at sixteen.4% share, even as IBM takes 0.33 with 10.7%.
total combined performance of all 500 supercomputers has jumped significantly, from 420 petaflop/s six months ago to 566.7 now. 90-5 systems at the list now exceed one petaflop.
here’s the modern list of the ten quickest supercomputers in the world:
1. TaihuLight: Sunway MPP, SW26010; country wide Supercomputing center in Wuxi, China; 10.6 million cores (ninety three.01 petaflop/s).
2. Tianhe-2: TH-IVB-FEP Cluster; countrywide terrific laptop middle in Guangzhou, China; three.12 million cores (33.86 petaflop/s).
three. Titan: A Cray XK7 system on the department of electricity’s very wellRidge countrywide Laboratory (17.fifty nine petaflop/s).
four. Sequoia: An IBM BlueGene/Q gadget placed at the department of electricity’s Lawrence Livermore national Lab in California, with 1.fifty seven million cores.
five. k computer: A SPARC64 machine with 705k cores at RIKEN superior Institute for Computational technological know-how in Japan.
6. Mira: IBM BlueGene/Q; DOE/SC/Argonne countrywide Laboratory, US; 786k custom IBM cores.
7. Trinity: Cray XC40; DOE/NNSA/LANL/SNL, US; 301,056 Xeon E5-2698v3 cores.
eight. Piz Daint: Cray XC30 with 116k Xeon and Nvidia cores; placed at the Swiss national Computing Centre in Switzerland.
nine. Hazel bird: Cray XC40; HRLS-Höchstleistungsrechenzentrum Stuttgart, Germany; 185k Xeon E5-2680v3 cores.
10. Shaheen II: A Cray XC40 at King Abdullah’s university of technology and generation in Saudi Arabia, marking the primary appearance of a middle East supercomputer inside the top 10 (5.536 petaflop/s).
