Recently, the Harvard-Smithsonian Center for Astrophysics unveiled an unprecedented simulation of the universe’s development. Called the Illustris project, the simulation depicts more than 13 billion years of cosmic evolution across a cube of the universe that’s 350-million-light-years on each side. But why was it important to conduct such a simulation?
Creating a realistic computer simulation of how light suffuses a room is crucial not just for animated movies like Toy Story or Cars, but also in industry. Special computing methods should ensure this, but require great effort. Computer scientists from Saarbrücken have developed a novel approach that vastly simplifies and speeds up the whole calculating process.
Physicists have created a tractor beam on water, providing a radical new technique that could confine oil spills, manipulate floating objects or explain rips at the beach. The group discovered they can control water flow patterns with simple wave generators, enabling them to move floating objects at will. The new technique gives scientists a way of controlling things adrift on water in a way that resembles sci-fi tractor beams.
A team representing Westinghouse Electric Company and the Consortium for Advanced Simulation of Light Water Reactors, a DOE Innovation Hub led by Oak Ridge National Laboratory, has received an HPC Innovation Excellence Award for applied simulation on Titan, the nation’s most powerful supercomputer. The award recognizes achievements made by industry users of high-performance computing technologies.
Using NASA's Hubble Space Telescope, a team of astronomers has spotted a star system that could have left behind a "zombie star" after an unusually weak supernova explosion. A supernova typically obliterates the exploding white dwarf, or dying star. On this occasion, scientists believe this faint...
When the space shuttle Columbia disintegrated on re-entry in 2002, sophisticated computer models were key to determining what happened. A piece of foam flew off at launch and hit a tile, damaging the leading edge of the shuttle wing and exposing the underlying structure. Temperatures soared to thousands of degrees as Columbia plunged toward Earth at 27 times the speed of sound, said Gallis, who used NASA codes and Icarus for simulations...
FLOW-3D 11 features FlowSight, an advanced visualization tool based on the EnSight post-processor, which offers powerful ways to analyze, visualize and communicate simulation data.

SystemModeler 4 is a physical modeling and simulation environment for cyber-physical systems. Using drag-and-drop from a large selection of built-in and expandable modeling libraries, users can build multi-domain models of their complete system.
Altair has announced its intent to acquire Visual Solutions, makers of VisSim, a visual language for mathematical modeling, simulation and model-based embedded system development used by scientists and engineers. The transaction is expected to close by the end of July 2014.
The Columbia River basin in the Pacific Northwest offers great potential for water power; hydroelectric power stations there generate over 20 000 megawatts already. Now a simulation model will help optimize the operation of the extensive dam system.
Every trillionth of a second, Panagiotis Grammatikopoulos calculates the location of each individual atom in a particle based on where it is and which forces apply. He uses a computer program to make the calculations, and then animates the motion of the atoms using visualization software. The resulting animation illuminates what happens, atom-by-atom, when two nanoparticles collide.
Ensemble forecasting is a key part of weather forecasting. Computers typically run multiple simulations using slightly different initial conditions or assumptions, and then analyze them together to try to improve forecasts. Using Japan’s K computer, researchers have succeeded in running 10,240 parallel simulations of global weather, the largest number ever performed, using data assimilation to reduce the range of uncertainties.

Michael M. Resch, the Director of the Stuttgart High Performance Computing Center (HLRS) will be talking about “HPC and Simulation in the Cloud – How Academia and Industry Can Benefit.” His keynote is of special interest to cloud skeptics, given that prior to 2011, Resch himself was a vocal cloud pessimist. Three years later, he feels that this technology provides a practical option for many users.
