Green500 Reaches New Heights in Energy-Efficient Supercomputing

The new Green500 list of the most energy-efficient supercomputers demonstrates some significant progress from last year. Thanks to the new manycore processors from Intel and NVIDIA that are starting to penetrate the top systems, performance per watt numbers are on the rise.

AI Shapes Supercomputing; Processor News Plus Green500

Episode 152: Addison Snell and Michael Feldman wrap up the Supercomputing 16 show with an overview of AI and the Green500 list.

TACC Flips the Switch on Solar-Powered Supercomputer

The Texas Advanced Computing Center in Austin has installed the world’s largest solar-powered HPC system. The 400 teraflop supercomputer, known as Hikari, is an HPE Apollo 800 cluster that uses technology supplied by Japanese green energy specialist NTT FACILITIES. In addition to taking advantage of Austin’s abundant sunshine, the power setup also employs high voltage direct power (HVDC) to further reduce energy consumption.

Aquila Takes Wraps Off Liquid-Cooled HPC Server

Aquila, a system provider based in Albuquerque, New Mexico, has unveiled a new liquid-cooled server platform that offers one of the densest and most energy-efficient architectures in the market. The platform, known as Aquarius, uses a patented warm water cooling technology along with rack-level power distribution to minimize energy consumption and allow for very high levels of computational density.

Supercomputing Gets a Shot in the ARM

The prospects for another serious rival to the x86 processor in the high performance computing space are looking much better this week after ARM Holdings presented the company’s plan to offer an HPC version of its 64-bit architecture. Known as ARMv8-A SVE, the design incorporates a technology known as the Scalable Vector Extension (SVE), which will provide a unique type of flexibility with regard to vector processing -- the basis of many scientific and engineering workloads.

Energy Efficiency Advances Sluggish on Latest Green500 List

The 19th edition of the Green500 was released today with the usual array of accelerated systems at the top of the list and a plethora of energy-sipping x86 clusters comprising the remainder. For the most part though, energy efficiency gains slowed over the past 12 months after chalking up some pretty impressive gains in previous years. 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.
