Heterogeneous Systems Re-Claim Green500 List Dominance
SALT LAKE CITY, UT - November 14, 2012 - The latest Green500 List was released today (http://www.green500.org/lists/green201211) and the top spots on the list have been taken over by machines that combine commodity processors with coprocessors or graphics processing units (GPUs) to form heterogeneous high-performance computing systems.
With all eyes on the new TOP500 number one system, Oak Ridge National Labs' Titan, it was a system belonging to a neighbor at the University of Tennessee that debuted at the top of the November Green500 List. The National Institute for Computational Sciences' Beacon system has set the new energy efficiency bar at nearly two-and-a-half billion floating-point operations per second (gigaflops) per watt. Employing Intel's Sandy Bridge series of Xeon central processing units (CPUs) and four of Intel's Xeon Phi coprocessors per node Beacon achieved a peak 112,200 gigaflops of performance running the LINPACK benchmark while consuming only 44.89 kW of power.
The Intel Xeon Phi--"Knights Corner"-- is a 22nm multicore coprocessor featuring the world's first 3D Tri-Gate transistors. Like its GPU counterparts, the Intel Xeon Phi resides on a PCI Express board that plugs into a machine's expansion slots.

Growing Greenness in the Grassroots Green500
June 30, 2011 – The latest release of The Green500 List points to a rapidly increasing pace of greenness on the Green500 List. Of the ten greenest supercomputers in the world, two trends towards greener supercomputing have emerged: (1) aggregating many low-power processors a la IBM BlueGene/Q and the K Computer by Fujitsu at the RIKEN Advanced Institute for Computational Science and (2) using energy-efficient accelerators, typically from the gaming/graphics market, e.g., AMD Radeon GPU, NVIDIA Tesla Fermi GPU, Cell, and Intel Knights Corner, to complement the commodity CPUs from Intel and AMD.
The Green500 has ranked the energy efficiency of the world‟s 500 fastest supercomputers since its debut in 2007, serving as a complement to the well-known supercomputer industry marker TOP500. Green500 founder Wu Feng notes that “The Green500 seeks to raise awareness in the energy efficiency of supercomputing, and in turn, drive energy efficiency as a first-order design constraint – one that is on par with performance or speed.” To measure this energy efficiency, the Green500 uses a metric defined as „millions of floating-point operations per second‟ (MFLOPS) divided by „watts‟ (W) or MFLOPS/W.

With the latest release of The Green500 List, accelerator-based supercomputers now occupy the top eight slots of the Green500, where the fuel efficiency (or energy efficiency) of supercomputers is defined as millions of floating-point operations per second (MFLOPS) divided by watts (W) or MFLOPS/W. Accelerators refer to the use of dedicated hardware to perform computations faster than a traditional processor, also known as a central processing unit (CPU).

In the inaugural episode of the Green HPC podcast series we will examine the issues that datacenter managers and system designers are facing with high performance computing systems of all sizes today. Even if you aren’t “green at heart,” there are very practical and compelling reasons why a growing awareness of energy use in your datacenter — how much, where it goes, and what it costs you — is critical to your success.

The sixth edition of the Green500 List shows a continuing improvement in energy efficiency among the world's fastest supercomputers. Three IBM QPACE (quantum chromodynamics parallel computing on the Cell) top the latest Green500 list, all tying for first place and all are located in Germany: Jülich Research Center, University of Regensburg, and University of Wuppertal.

On November 19, three matching German supercomputers easily won the latest Green500 prize, which rewards not just raw computing power but energy efficiency. The machines, at the Research Center of Jülich and the universities of Regensburg and Wuppertal, were designed for high-energy-physics calculations as part of the "QPACE" project.

Purdue University's student Cluster Challenge team at the SC09 supercomputing conference in Portland, Ore., was fast and green. The Purdue team in the competition, where teams of undergraduates from around the country pushed their student-run supercomputers to the maximum over three days, won the award for getting the most done on the least amount of power, organizers announced Thursday (Nov. 19). Purdue also won the power consumption award last year.

The Green500 is getting a refresh. Since its 2007 debut, the Green500 has ranked only the energy efficiency of the world's 500 fastest performing supercomputers. Now, the Green500 is expanding the definition of a supercomputer to include a wider spectrum of the high-end computing world with the 'Little Green500' list and opening its doors to innovation with two new exploratory lists: the 'Open Green500' and 'HPCC Green500.'

On Wednesday, November 19, at SC|08, the founders of the Green500 from Virginia Tech will host a Birds-of-a-Feather (BoF) session, centered around evolving the list to better serve the high-performance computing community. Being "green" has undergone a true revolution -- from being largely scoffed at in the early 2000s to being so important that being "green" has become a necessity rather than a luxury.
