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.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
