FRANKFURT, Germany; BERKELEY, Calif.; and KNOXVILLE, Tenn.—The TOP500 celebrates its 25th anniversary with a major shakeup at the top of the list. For the first time since November 2012, the US claims the most powerful supercomputer in the world, leading a significant turnover in which four of the five top systems were either new or substantially upgraded.
IBM and its partners have developed a novel technology to build 5nm chips, based on silicon nanosheet transistors. Compared to 10nm chips using FinFET transistors, the new technology promises to deliver a 40 percent performance increase, a 75 percent power savings, or some combination of the two.
Ministers from seven European countries have signed on to a plan to develop an exascale capability based on technology developed within the EU member states. The goal is to bring up two pre-exascale supercomputers by 2020 and two full exascale systems no later than 2023.
The long-predicted demise of Moore’s Law appears to be playing out. Over the last couple of years, Intel and other chipmakers have struggled to keep their semiconductor technology plans on schedule, paving the way for fundamental changes in the computer industry.
The National Aeronautics and Space Administration (NASA) has built a new modular supercomputing facility at its Ames Research Center in Silicon Valley that could be the template for future HPC infrastructure at the agency.
The Tokyo Institute of Technology, also known as Tokyo Tech, has revealed that the TSUBAME 3.0 supercomputer scheduled to be installed this summer will provide 47 half precision (16-bit) petaflops of performance, making it one of the most powerful machines on the planet for artificial intelligence computation. The system is being built by HPE/SGI and will feature NVIDIA’s Tesla P100 GPUs.
The Latest List - June 2018
The top three positions in the Green500 are all taken by supercomputers installed in Japan that are based on the ZettaScaler-2.2 architecture using PEZY-SC2 accelerators, while all other system in the top 10 use NVIDIA GPUs.
The most energy-efficient supercomputer is once again the Shoubu system B, a ZettaScaler-2.2 system installed at the Advanced Center for Computing and Communication, RIKEN, Japan. It was remeasured and achieved 18.4 gigaflops/watt during its 858 teraflops Linpack performance run. It is ranked number 362 in the TOP500 list.
The second-most energy-efficient system is Suiren2 system at the High Energy Accelerator Research Organization/KEK, Japan. This ZettaScaler-2.2 system achieved 16.8 gigaflops/watt and is listed at position 421 in the TOP500. Number three on the Green500 is the Sakura system installed at PEZY Computing. It achieved 16.7 gigaflops/watt and occupies position 388 on the TOP500 list.
They are followed by the DGX SaturnV Volta system in the US; the Summit system in the US, the TSUBAME 3.0 system, AIST AI Cloud system, the AI Bridging Cloud Infrastructure (ABCI) system, all from Japan; the new IBM MareNostrum P9 cluster in Spain; the DOE’s Summit system; and Wilkes-2, from the UK. All of these systems use various NVIDIA GPUs.
The most energy-efficient supercomputer that doesn’t rely on accelerators of any kind is the Sunway TaihuLight, which is powered exclusively by ShenWei processors. Its 6.05 gigaflops/watt earned it 22nd place on the Green500 list.
The Green500 list ranks the top 500 supercomputers in the world by energy efficiency. The focus of performance-at-any-cost computer operations has led to the emergence of supercomputers that consume vast amounts of electrical power and produce so much heat that large cooling facilities must be constructed to ensure proper performance. To address this trend, the Green500 list puts a premium on energy-efficient performance for sustainable supercomputing.
The inaugural Green500 list was announced on November 15, 2007 at SC|07. As a complement to the TOP500, the unveiling of the Green500 ushered in a new era where supercomputers can be compared by performance-per-watt.
While the selection of any power-performance metric will be controversial, we currently opt for "FLOPS-per-Watt" given that it has already become a widely used metric in the community and for reasons outlined in, Making a Case for a Green500 List, which was presented at the 2nd IEEE IPDPS Workshop on High-Performance, Power-Aware Computing, April 2006.
At SC|09, the Green500 announced the creation of three new exploratory lists -- Little, Open, and HPCC -- as companions to the Green500 list. While the Green500 list continues to be the official rankings, these new lists allow us to explore new metrics based on community input.
