Mira science run probes turbulence physics

Earlier this month, University of Texas’s Robert Moser initiated the first full-scale production run on Mira, the ALCF’s new 10-petaflops system. Moser is examining the complex physics of a specific region of wall-bounded turbulence, which is central to understanding the energy losses inherent in transportation. Moser’s work addresses energy loss at many scales, from vehicles moving through air or water, to fluids transported through the pipes and ducts that comprise urban infrastructure. The team developed their code specifically to exploit Mira’s capabilities, and this recently-launched investigation aims to develop a nearly complete understanding of the phenomena dominating this type of turbulence. One week into his campaign and 47 million core-hours later, the team is closer to reaching that goal. The remaining jobs of Moser’s campaign executed in the coming days, over 100 million core-hours in total, should yield even better insights.
