TOP500 Meanderings: Sluggish Performance Growth May Portend Slowing HPC Market

For all the supercomputing trends revealed on recent TOP500 lists, the most worrisome is the decline in performance growth that has taken place over the over the last several years – worrisome not only because performance is the lifeblood of the HPC industry, but also because there is no definitive cause of the slowdown.

New Five Nanometer Transistor Unveiled by IBM and Cohorts

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.

EU Outlines Plan to Develop Home-Grown Exascale Supercomputers

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.

Moore’s Law Is Breaking Down, But That’s OK

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.

NASA Buys into Modular Supercomputing with New Facility that Saves Energy and Water

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.

Next-Generation TSUBAME Will Be Petascale Supercomputer for AI

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. More News

About 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.
