Mike Bernhardt interviews Georg Hager, Captain of last year’s winning Team from Germany in the Intel Parallel Universe Computing Challenge (PUCC) at SC13.
“The Argonne Training Program on Extreme-Scale Computing (ATPESC) provides intensive hands-on training on the key skills, approaches, and tools to design, implement, and execute computational science and engineering applications on current high-end computing systems and the leadership-class computing systems of the future. As a bridge to that future, this two-week program fills the gap that exists in the training computational scientists typically receive through formal education or other shorter courses.”
“All of these problems require simulations with extremely high dynamic range in space and time, complex physics (including radiation transport and non-equilibrium gas chemistry), and large simulation volumes. We use the Enzo code (enzo-project.org), which has been modified to scale to large core counts on Blue Waters, which is the only machine available where the heavy data and communication needs can be satisfied.”
This simulation visualizes a coaxial jet flow as it can be found in the exhaust of modern jet engines that are used for aircraft propulsion. The visualization highlights the flow instability process and the transition from laminar to turbulent flow. Intensive mixing between the heated primary jet and the cold bypass flow lead to strong noise radiation.
“The goal at Airbus is to create a single fully integrated simulation-driven design process. He explained that they are developing simulation to the point where it is implemented from “conceptual design, to detailed design, all the way to the certification of the aircraft and finally to the continued development of the aircraft.”
