A team of computer scientists, mathematicians and geophysicists have optimized the SeisSol earthquake simulation software on the SuperMUC high performance computer to push its performance beyond the “magical” one petaflop/s mark — one quadrillion floating point operations per second.
Somewhere out in the cosmos an ordinary galaxy spins, seemingly at slumber. Then all of a sudden, WHAM! A flash of light explodes from the galaxy's center. A star orbiting too close to the event horizon of the galaxy's central supermassive black hole has been torn apart by the force of gravity, heating up its gas and sending out a beacon to the far reaches of the universe.
Michigan researchers say mathematical formulas suggest it's possible to adjust to new time zones a bit faster than previously thought, and they created their own free app to help. In a study partly funded by the Air Force, the team used two equations proven to predict someone's circadian rhythm, and with computer modeling calculated different schedules of light exposure for more than 1,000 possible trips.
Suppose you’re trying to navigate an unfamiliar section of a big city, and you’re using a particular cluster of skyscrapers as a reference point. Traffic and one-way streets force you to take some odd turns and, for a while, you lose sight of your landmarks. When they reappear, in order to use them for navigation, you have to be able to identify them as the same buildings you were tracking before — as well as your orientation...
A revolutionary new method of encrypting confidential information has been patented by scientists who were inspired by discoveries from human biology, which model how the heart and lungs coordinate their rhythms by passing information between each other.
In theory, doubling the number of cores doubles the chip’s efficiency, but splitting up computations so that they run efficiently in parallel isn’t easy. On the other hand, say a trio of computer scientists from MIT, Israel’s Technion, and Microsoft Research, neither is it as hard as had been feared.
Einstein's scepticism about quantum mechanics may lead to an ultra-secure Internet. Entangled particles stay connected even when separated by large distances.
ACM Turing Award Goes to Leslie Lamport for Work Enabling Distributed Computing in Data Center, Security, Cloud LandscapesMarch 19, 2014 9:33 am | by The Association for Computing Machinery | News | Comments
The Association for Computing Machinery has named Leslie Lamport, a Principal Researcher at Microsoft Research, as the recipient of the 2013 ACM A.M. Turing Award for imposing clear, well-defined coherence on the seemingly chaotic behavior of distributed computing systems, in which several autonomous computers communicate with each other by passing messages.
Ben Recht is looking for problems. He develops mathematical strategies to help researchers, from urban planners to online retailers, cut through blizzards of data to find what they’re after. He resists the “needle in the haystack” metaphor because, he says, the researchers, engineers and business people he has worked with usually don’t know enough about their data to reach their goal.
As the amount of data grows ever larger but memory speed continues to greatly lag CPU speed, Xian-He Sun has established a new mathematical model for reducing data access delay. Sun is creator of Sun-Ni’s law — one of three scalable computing laws along with Amdahl’s law and Gustafson’s law — and Distinguished Professor of Computer Science at Illinois Institute of Technology.
NASA’s Asteroid Data Hunter contest series will offer $35,000 in awards over the next six months to citizen scientists who develop improved algorithms that can be used to identify asteroids. This contest is being conducted in partnership with Planetary Resources of Bellevue, WA.
The 10-day tour of Europe was not your typical itinerary — Garching, Karlsruhe, Villigen, Hamburg and Oxford. In January. But David Brown and Craig Tull of the Computational Research Division and Alex Hexemer of the Advanced Light Source weren’t touring to see the sights — they more interested in seeing the lights — powerful scientific instruments known as light sources that use intense X-rays to study materials
The Department of Energy’s National Energy Research Scientific Computing Center (NERSC) announced the winners of its second annual High Performance Computing (HPC) Achievement Awards on February 4, 2014, during the annual NERSC User Group meeting at Lawrence Berkeley National Laboratory (Berkeley Lab).
A large number of neglected diseases exist in which each disease has only a small number of patients in the world, yet the number is still significant. Kun-Yi Hsin is working on precisely this problem. In a recent article, he describes his work identifying potential drugs and targets for those drugs using a computational approach that has the potential to bring the cost of drug development down while increasing the speed of drug discovery.
The scientists and inventors who make big-screen superheroes, spectacular explosions and other only-in-the-movies effects possible have their own Oscar ceremony. Kristen Bell and Michael B. Jordan hosted the film academy's Scientific and Technical Awards February 15, 2014, at the Beverly Hills Hotel, recognizing more than 50 of the most creative scientists and engineers in the movie business.
People who appreciate the beauty of mathematics activate the same part of their brain when they look at aesthetically pleasing formula as others do when appreciating art or music, suggesting that there is a neurobiological basis to beauty. There are many different sources of beauty — a beautiful face and a great symphony are examples of beauty derived from sensory experiences. But there are other, highly intellectual sources of beauty.
A Lawrence Livermore National Laboratory physicist and his colleagues have found a new application for the tools and mathematics typically used in physics to help solve problems in biology. Specifically, the team used statistical mechanics and mathematical modeling to shed light on something known as epigenetic memory — how an organism can create a biological memory of some variable condition, such as quality of nutrition or temperature.
Alan Turing: His Work and Impact, was selected for the top honor, R.R. Hawkins Award, at the 38th annual PROSE Awards.
