An international team of researchers used computer modeling to reveal, for the first time, how giant swirls form during the collision of tectonic plates, with subduction zones stuttering and recovering after continental fragments slam into them.
An experimental team at the University of Leeds and mathematicians at the University of York have developed a mathematical model to explain how RNA viruses solve this enormously complicated “Rubik’s cube” in microseconds or milliseconds.
Football, aka soccer, fascinates millions of fans, almost all of them unaware that the game is subject to the laws of physics. Despite their seemingly arbitrary decisions, players obey certain rules, as they constantly adjust their positions in relation to their teammates, opponents, the ball and the goal. Scientists have analyzed the time-dependent fluctuation of both the ball and all players’ positions throughout an entire match.
Microway NumberSmasher GPU-accelerated platforms are available pre-configured for optimal performance ofCST STUDIO SUITE. These systems are convertible between 4U rackmount and tower configurations supporting NVIDIA Tesla K40, K20X and K20.
The Obama administration hopes to fight global warming with the power of numbers, maps and even gaming-type simulations. The White House on March 19, 2014, announced an initiative to provide private companies and local governments better access to already public climate data. The idea is that, with this localized data, they can help the public understand the risks they face, especially in coastal areas where flooding is a big issue.
A powerful, new three-dimensional model provides fresh insight into the turbulent death throes of supernovas, whose final explosions outshine entire galaxies and populate the universe with elements that make life on Earth possible. The model is the first to represent the start of a supernova collapse in three dimensions, said its developer
By the end of the 21st century, some parts of the world can expect as many as 30 more days a year without precipitation, according to a new study by Scripps Institution of Oceanography, UC San Diego researchers. Ongoing climate change caused by human influences will alter the nature of how rain and snow falls; areas that are prone to dry conditions will receive their precipitation in narrower windows of time.
Next week, Scientific Computing will host a live panel discussion that looks at how a unique supercomputing system, created to serve the needs of a scientific community alliance in seven northern German states, has unified datacenter resources to address big data challenges. By streamlining the analysis process through automation, the HLRN alliance has improved performance and increased accuracy, resulting in greater efficiency.
A unique method to collect rain water samples during Hurricane Sandy has revealed the storm's chemical "signature" with a new level of detail. The technique may also lead to weather model advances that will ultimately improve storm prediction. Hurricane Sandy, also known as Superstorm Sandy, was the deadliest and most destructive hurricane of the 2012 Atlantic hurricane season. Nearly 300 people perished along the path of the storm.
Using data from NASA's Van Allen Probes, researchers have tested and improved a model to help forecast what's happening in the radiation environment of near-Earth space -- a place seething with fast-moving particles and a space weather system that varies in response to incoming energy and particles...
The Galápagos Islands are home to some of the most active volcanoes in the world, with more than 50 eruptions in the last 200 years. Yet until recently, scientists knew far more about the history of finches, tortoises, and iguanas than of the volcanoes on which these unusual fauna had evolved.
Astronomers at the University of Washington have developed a new method of gauging the atmospheric pressure of exoplanets, or worlds beyond the solar system, by looking for a certain type of molecule. And if there is life out in space, scientists may one day use this same technique to detect its biosignature — the telltale chemical signs of its presence — in the atmosphere of an alien world.
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).
Antarctica's Ross Sea is one of the few polar regions where summer sea-ice coverage has increased during the last few decades, bucking a global trend of drastic declines in summer sea ice across the Arctic Ocean and in two adjacent embayments of the Southern Ocean around Antarctica.
Lawrence Livermore has joined forces with two other national labs to deliver next generation supercomputers able to perform up to 200 peak petaflops (quadrillions of floating point operations per second), about 10 times faster than today's most powerful high performance computing (HPC) systems.
Multi-scale Simulation Software for Chemistry Research Developed Using Trestles and Gordon SupercomputersFebruary 19, 2014 6:48 pm | by San Diego Supercomputer Center | News | Comments
Researchers at the San Diego Supercomputer Center at the University of California, San Diego, have developed software that greatly expands the types of multi-scale QM%2FMM (mixed quantum and molecular mechanical) simulations of complex chemical systems that scientists can use to design new drugs, better chemicals, or improved enzymes for biofuels production.
Black holes may be dark, but the areas around them definitely are not. These dense, spinning behemoths twist up gas and matter just outside their event horizon, and generate heat and energy that gets radiated, in part, as light. And when black holes merge, they produce a bright intergalactic burst that may act as a beacon for their collision.
