TOP500 Meanderings: Supercomputers Take Big Green Leap in 2017

Over the last year, the greenest supercomputers in the world more than doubled their energy efficiency – the biggest jump since the Green500 started ranking these systems more than a decade ago. If such a pace can be maintained, exascale supercomputers operating at less than 20 MW will be possible in as little as two years. But that’s a big if.

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.

TOP500 List Refreshed, US Edged Out of Third Place

FRANKFURT, Germany; BERKELEY, Calif.; and KNOXVILLE, Tenn.— The 49th edition of the TOP500 list was released today in conjunction with the opening session of the ISC High Performance conference, which is taking place this week in Frankfurt, Germany. The list ranks the world’s most powerful supercomputers based on the Linpack benchmark and is released twice per year.

Fujitsu Unveils Circuit Design that Optimizes Deep Learning Applications

Fujitsu Laboratories has developed a circuit technology that is said to improve the energy efficiency of deep learning workloads. According to the company, it plans to commercialize the technology in 2018 as part of its Human Centric AI Zinrai initiative.

Google Reveals Technical Specs and Business Rationale for TPU Processor

Although Google’s Tensor Processing Unit (TPU) has been powering the company’s vast empire of deep learning products since 2015, very little was known about the custom-built processor. This week the web giant published a description of the chip and explained why it’s an order of magnitude faster and more energy-efficient than the CPUs and GPUs it replaces.

Cray to Deliver ARM-Powered Supercomputer to UK Consortium

Cray is going to build what will looks to be the world’s first ARM-based supercomputer. The system, known as “Isambard,” will be the basis of a new UK-based HPC service that will offer the machine as a platform to support scientific research and to evaluate ARM technologies for high performance computing. Installation of Isambard is scheduled to begin in March and be up and running before the end of the year.

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.
