Slimming Down Supercomputers

DOE Office of Science

Scientists curb the energy appetite of the nation’s “answer machines.” At the Argonne Leadership Computing Facility in Illinois, supercomputing systems like Mira and its cohorts take on cooling directly. Instead of first chilling a stream of air and then puffing it into the computer's racks,...

Scientists challenge conventional wisdom to improve predictions of the bootstrap current

Princeton Plasma Physics Laboratory

Using Mira, researchers from Princeton Plasma Physics Laboratory (PPPL) have challenged understanding of a key element in fusion plasmas. At issue has been an accurate prediction of the size of the “bootstrap current” — a self-generating electric current — and an understanding of what carries...

New discovery may help engineers design quieter jet airplanes

Space Daily

Researchers from the University of Minnesota report in Physics of Fluids, from AIP Publishing, the development of a new approach to studying turbulence in jets. Their approach led to the discovery of new coherent modes - parts of the fluid that flow in predictable patterns - associated with the...
