“I’d like to propose that we routinely compare machines using the metric of data motion capacity, or their ability to move data quickly,” Snavely told attendees of the ‘Get Ready for Gordon – Summer Institute’ being held this week (August 8-11) at SDSC to familiarize potential users with the unique capabilities of SDSC’s new Gordon data-intensive supercomputer.
Gordon, the result of a five-year, $20 million award from the National Science Foundation (NSF), is the first high-performance supercomputer to use large amounts of flash-based SSD (solid state drive) memory. With about 300 trillion bytes of flash memory and 64 I/O nodes, Gordon will be capable of handling massive data bases while providing up to 100 times faster speeds when compared to hard drive disk systems for some queries. Flash memory is more common in smaller devices such as mobile phones and laptop computers, but unique for supercomputers, which generally use slower spinning disk technology.
The system is set to formally enter production on January 1, 2012, although pre-production allocations on some parts of the cluster will start as early as this month for U.S. academic researchers.
“This may be a somewhat heretical notion, but at SDSC we want a supercomputer to be data capable, not just FLOP/S capable,” said Snavely, whom along with many other HPC experts now contend that supercomputers should also be measured by their overall ability to help researchers solve real-world science problems. Snavely’s proposal includes a measurement that weights DRAM, flash memory, and disk capacity according to access time in a compute cycle.A common term within the supercomputing community, peak speed means the fastest speed at which a supercomputer can calculate. It is typically measured in FLOP/S, which stands for FLoating point OPerations per Second. In lay terms, it basically means peak calculations per second. In June, a Japanese supercomputer capable of performing more than 8 quadrillion calculations per second (petaflop/s) was ranked the top system in the world, putting Japan back in the top spot for the first time since 2004, according the latest edition of the TOP500 List of the world’s supercomputers. The system, called the K Computer, is at the RIKEN Advanced Institute for Computational Science (AICS) in Kobe, Japan, and replaced China's Tianhe-1A system as the fastest supercomputer in the rankings, which has been using this metric since 1993.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
