In what has to be one of the most beautiful simulations I’ve ever seen, this video from the European Space Agency shows simulated interaction of solar winds with 67P/Churyumov-Gerasimenko, the famous comet targeted the Rosetta mission. “The simulated conditions represent those expected at 1.3 AU from the Sun, close to perihelion, where the comet is strongly active.”
“Sea level rise is one of the most visible signatures of our changing climate, and rising seas have profound impacts on our nation, our economy and all of humanity,” said Michael Freilich, director of NASA’s Earth Science Division. “By combining space-borne direct measurements of sea level with a host of other measurements from satellites and sensors in the oceans themselves, NASA scientists are not only tracking changes in ocean heights but are also determining the reasons for those changes.”
“Researchers at the U.S. Department of Energy’s Argonne National Laboratory will be testing the limits of computing horsepower this year with a new simulation project from the Virtual Engine Research Institute and Fuels Initiative (VERIFI) that will harness 60 million computer core hours to dispel those uncertainties and pave the way to more effective engine simulations.”
Over at TACC, Jorge Salazar writes that new supercomputer simulations are helping doctors improve the repair and replacement of heart valves. “New supercomputer models have come closer than ever to capturing the behavior of normal human heart valves and their replacements, according to recent studies by groups including scientists at the Institute for Computational Engineering and Sciences (ICES) at The University of Texas at Austin and the Department of Mechanical Engineering atIowa State University.”
The Embree kernel approach, using the Intel Xeon Phi coprocessor is applicable to many situations. The implementation can be tuned to the hardware available, using different vector widths and workloads per ray. With a flexible toolkit for rendering, applications can take advantage of the latest hardware acceleration to achieve maximum performance.
“Since Hurricane Katrina made landfall in 20015, storm prediction technology has seen dramatic forward movement, from improved software to better use of observations and increased computing power – all aimed at giving emergency decision makers more time and specifics to help protect lives and property. The expert panelists in this Congressional Briefing outline research advances that have led to better forecasting of hurricane and tropical storm weather and impacts. And they spotlight research directions that hold promise for future improvements.”
