“SpaceX is designing a new, methane-fueled engine powerful enough to lift the equipment and personnel needed to colonize Mars. A vital aspect of this effort involves the creation of a multi-physics code to accurately model a running rocket engine. The scale and complexity of turbulent non-premixed combustion has so far made it impractical to simulate, even on today’s largest supercomputers. We present a novel approach using wavelets on GPUs, capable of capturing physics down to the finest turbulent scales.”
“The Argonne Leadership Computing Facility’s (ALCF) mission is to accelerate major scientific discoveries and engineering breakthroughs for humanity by designing and providing world-leading computing facilities in partnership with the computational science community. We help researchers solve some of the world’s largest and most complex problems with our unique combination of supercomputing resources and expertise.”
“By using high performance visualization systems, researchers at the Scientific Computing and Research Institute are using deep brain stimulation to treat several disabling neurological symptoms—most commonly the debilitating motor symptoms of Parkinson’s disease, such as tremor, rigidity, stiffness, slowed movement, and walking problems. The procedure reduces patient treatment time from four to five hours to less than 10 minutes. The result for the patient is restored movement and a more normal life.”
“Written by one of the foremost experts in high-performance computing and the inventor of Gustafson’s Law, The End of Error: Unum Computing explains a new approach to computer arithmetic: the universal number (unum). The unum encompasses all IEEE floating-point formats as well as fixed-point and exact integer arithmetic. This new number type obtains more accurate answers than floating-point arithmetic yet uses fewer bits in many cases, saving memory, bandwidth, energy, and power.”
Because the requirements in terms of energy, emissions, and fuel efficiency have not been globally standardized, vehicle manufacturers are making use of increasingly sophisticated simulation to get new vehicles developed as quickly and cheaply as possible while making sure their newest models meet these standards.
