The TOP500 list provides international rankings of general-purpose HPC systems that are in common use for high-end applications. Twice a year, in June and November, a new list featuring the sites operating the 500 most powerful computer systems is assembled and released. The project was started in 1993 to provide a reliable basis for tracking and detecting trends in high-performance computing.
The 2015 ISC High Performance Conference concluded its 30th meeting last week drawing 2,846 attendees, exceeding its own expectations. The organizers had initially expected around 2,600 to attend this year’s conference and exhibition, held in Frankfurt Germany from July 12 to 16. Also at the event were 153 leading high performance computing vendors and research organizations from around the world, who exhibited from July 13 to 15.
Last week, at the ISC High Performance conference, there was one announcement that might have escaped your attention. For the first time, EDR 100Gb/s solutions appeared on the TOP500 list. This is significant because it marks the transition from networks constructed around 40 and 56Gb/s fabrics to ones of 100Gb/s. Likewise, in the Ethernet market, hyper-scale data centers are also making the transition from 40Gb/s to 100Gb/s networks.
Giant stars die a violent death. After a life of several million years, they collapse into themselves and then explode in what is known as a supernova. How these stars explode remains a mystery. However, recent work led by Michigan State University may bring some answers to this astronomical question, detailing development of a three-dimensional model of a giant star’s last moments.
A NASA camera on the Deep Space Climate Observatory satellite has returned its first view of the entire sunlit side of Earth from one million miles away. This color image was generated by combining three separate images to create a photographic-quality image. The camera takes a series of 10 images using different narrowband filters to produce a variety of science products. Red, green and blue channel images are used.
When a power company wants to build a new wind farm, it generally hires a consultant to make wind speed measurements at the proposed site for eight to 12 months. Those measurements are correlated with historical data and used to assess the site’s power-generation capacity. MIT researchers will present a new statistical technique that yields better wind-speed predictions, even when it uses only three months’ worth of data.
Cloud, as one of the substantial transformative forces, is impacting all areas of IT supply, composition and consumption, and provides the basis for many big data, mobile and social solutions. In fact, International Data Corporation (IDC) predicts the number of new cloud-based solutions will triple in the next four to five years and that public cloud computing will reach almost $70 billion in 2015 worldwide.
Surfer 13, scientific graphics software accurately transforms XYZ data into presentation-ready maps. The gridding and contour mapping software, used by geologists, hydrologists and engineers, offers 13 different gridding methods, including Kriging with variograms, to convert irregularly spaced XYZ data into a uniform grid.
Sketch-a-Net is capable of correctly identifying the subject of sketches 74.9 percent of the time, compared to humans' 73.1 percent. As sketching becomes more relevant with the increase in use of touchscreens, it could provide a foundation for new ways to interact with computers. The research also showed the program performed better at determining finer details, such as specific bird variants.
The 20X image shows a brain slice of a mouse, cut through the hippocampus, which is a region critical for memory. Neuronal dendrites receive signals from other neurons and here they are labeled in blue forming an incredibly dense network. The supporting glial cells intertwine within this dendritic network in an equally complex manner and here are labeled in yellow.
Using New Horizons closest-approach images, NASA has created a simulated flyover of Pluto’s icy Norgay Mountains and Sputnik Plain, which make up the dwarf planet’s equatorial Tombaugh Region. After a decade-long, three-billion-mile journey, the images were acquired on July 14, 2015, during New Horizon’s closest approach at a distance of 48,000 miles. Features as small as a half-mile across are visible.
Marking 46 years since the 1969 moon landing, the Smithsonian National Air and Space Museum has launched a crowdsourcing project that would help to conserve and digitize the famous Apollo 11 spacesuit Neil Armstrong wore when he first set foot on the moon in time for the 50th anniversary of the Apollo Moon landing.
With space shuttles now housed in museums, innovators in aerospace are thinking of newer, better ways humans could reach space. One idea: What about a space elevator? This real idea is one simulation that's part of a high-tech interactive exhibition about the future of flight opening at the National Air and Space Museum. Designers have been developing "The Ultimate Interactive Flight Exhibition" with Boeing, NASA and the Smithsonian.
Researchers and amateur astronomers have discovered a very rare type of binary star system: the first known such system where one star completely eclipses the other. In the two-star system, a Cataclysmic Variable, a super dense white dwarf is stealing gas from its companion star, and both stars have lost all of their hydrogen. The highly-unusual system could be an important laboratory for studying ultra-bright supernova explosions.
Almost 100 years ago, astronomers discovered that the spectrum of starlight arrived on earth with dark gaps, so-called interstellar bands. Ever since, researchers have been trying to find out which type of matter in space absorbs the light and is responsible for these “diffuse interstellar bands” (DIB) of which over 400 are known today.
