On the heels of a successful ISC14 in Leipzig, Germany, last week, the latest Green500 list was just published, and once again the TSUBAME-KFC is the world’s greenest supercomputer with an energy efficiency of 4.4 gigaflops per watt. This system from Tokyo Institute of Technology broke the 4.0 gigaflops per watt mark last November, and it’s still Read more…
Unlike this November’s TOP500 list, which had very little churn in the top 10 (only one new system, Piz Daint, squeezed into the elite club) the most recent Green500 list’s upper echelon was filled with nothing but newcomers. While most are liquid-cooled, taking second place is an energy-efficient air-cooled supercomputer from the University of Cambridge, Read more…
Twice a year, in step with the biannual TOP500 list, the Green500 list ranks the most powerful systems in the world based on energy-efficiency. Published Wednesday evening at SC13, this year’s Green500 list continues a trend from previous years, the rise of heterogenous supercomputing. The latest list shows that the top 10 greenest systems are Read more…

NVIDIA credits its new GPU accelerators, along with Eurotech’s on-board hot-water cooling system. But Intel has something called the Xeon Phi.

Thanks to the hard work of the list keepers, we currently enjoy three major ones to review, compare and contrast: TOP500, Green500 and Graph 500. Each focuses on a distinct aspect of HPC – number crunching, energy efficiency, and data crunching, respectively – and together they allow us to construct our own type of Triple Crown.
<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/Blue_Gene_Q_rack_blue.jpg” alt=”” width=”82″ height=”103″ />The latest Green500 rankings were announced last week, revealing that top performance and power efficiency can indeed go hand in hand. According to the latest list, the greenest machines, in fact the top 20 systems, were all IBM Blue Gene/Q supercomputers. Blue Gene/Q, of course, is the platform that captured the number one spot on the latest TOP500 list, and is represented by four of the ten fastest supercomputers in the world.

We’re now approaching the twentieth anniversary of the TOP500. In recent years, two additional lists have gained traction: the Green500 and the Graph 500. Would a few more lists be useful?
<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/hat_trick_500.bmp” alt=”” width=”88″ height=”48″ />In the world of high performance computing, there are three distinct metrics in play: number crunching speed, data crunching speed, and energy efficiency. Can a computer excel at all three, or is our best recourse to try for something less than a hat trick?
There’s more than one way to build energy efficient supercomputers.
If there was a dominating theme at the Supercomputing Conference this year, it had to be GPU computing.
