New Supercomputer Rankings for "Big Data" Machines Released

17.11.2011
The list of supercomputers entered in the Graph500 competition now features 50 competitors, up from nine in its initial release a year ago, said Sandia National Laboratories researcher Richard Murphy, chair of the Graph500 steering committee.

New rankings were released Tuesday in Seattle at SC2011, the international conference for high-performance computing.

NNSA/SC Blue Gene/Q Prototype II has risen to the top spot on the list and is the first National Nuclear Security Administration winner. Sandia’s Ultraviolet platform placed 10th using custom software, the Sandia Red Sky supercomputer dropped from 8th to 13th, and Dingus and Wingus, the insouciantly named Sandia prototype (Convey-based Field-Programmable Gate Array, or FPGA) platforms, placed 23rd and 24th, respectively.

The Graph500 stresses supercomputer performance on “big data” scaling problems rather than on the purely arithmetic computations measured by the Linpack Top500 and similar benchmarks. Graph500 machines are tested for their ability to solve complex problems involving random-appearing graphs, rather than simply for their speed in solving complex problems.

Such graph-based problems are found in the medical world, where large numbers of medical entries must be correlated; in the analysis of social networks, with their enormous numbers of electronically related participants; and in international security, where, for example, huge numbers of containers on ships roaming the world’s ports of call must be tracked.

“Companies are interested in doing well on the Graph500 because large-scale data analytics are an increasingly important problem area and could eclipse traditional high-performance computing (HPC) in overall importance to society,” said Murphy, whose committee receives input from 30 international researchers. Changes are implemented by Sandia, the Georgia Institute of Technology, the University of Illinois at Urbana-Champaign, Indiana University and others.

Big-data problems are solved by creating large, complex graphs with vertices that represent the data points — say, people on Facebook — and edges that represent relations between the data points — say, friends on Facebook. These problems stress the ability of computing systems to store and communicate large amounts of data in irregular, fast-changing communication patterns, rather than the ability to perform many arithmetic operations in succession. The Graph500 benchmarks indicate how well supercomputers handle such complex problems.

Im Focus: Better thermal conductivity by adjusting the arrangement of atoms

Adjusting the thermal conductivity of materials is one of the challenges nanoscience is currently facing. Together with colleagues from the Netherlands and Spain, researchers from the University of Basel have shown that the atomic vibrations that determine heat generation in nanowires can be controlled through the arrangement of atoms alone. The scientists will publish the results shortly in the journal Nano Letters.

In the electronics and computer industry, components are becoming ever smaller and more powerful. However, there are problems with the heat generation. It is...

Im Focus: First-ever visualizations of electrical gating effects on electronic structure

Scientists have visualised the electronic structure in a microelectronic device for the first time, opening up opportunities for finely-tuned high performance electronic devices.

Physicists from the University of Warwick and the University of Washington have developed a technique to measure the energy and momentum of electrons in...

Im Focus: Megakaryocytes act as „bouncers“ restraining cell migration in the bone marrow

Scientists at the University Würzburg and University Hospital of Würzburg found that megakaryocytes act as “bouncers” and thus modulate bone marrow niche properties and cell migration dynamics. The study was published in July in the Journal “Haematologica”.

Hematopoiesis is the process of forming blood cells, which occurs predominantly in the bone marrow. The bone marrow produces all types of blood cells: red...

Im Focus: Artificial neural network resolves puzzles from condensed matter physics: Which is the perfect quantum theory?

For some phenomena in quantum many-body physics several competing theories exist. But which of them describes a quantum phenomenon best? A team of researchers from the Technical University of Munich (TUM) and Harvard University in the United States has now successfully deployed artificial neural networks for image analysis of quantum systems.

Is that a dog or a cat? Such a classification is a prime example of machine learning: artificial neural networks can be trained to analyze images by looking...

Im Focus: Extremely hard yet metallically conductive: Bayreuth researchers develop novel material with high-tech prospects

An international research group led by scientists from the University of Bayreuth has produced a previously unknown material: Rhenium nitride pernitride. Thanks to combining properties that were previously considered incompatible, it looks set to become highly attractive for technological applications. Indeed, it is a super-hard metallic conductor that can withstand extremely high pressures like a diamond. A process now developed in Bayreuth opens up the possibility of producing rhenium nitride pernitride and other technologically interesting materials in sufficiently large quantity for their properties characterisation. The new findings are presented in "Nature Communications".

The possibility of finding a compound that was metallically conductive, super-hard, and ultra-incompressible was long considered unlikely in science. It was...
