  • Argonne's Sibendu Som

Turbocharging engine design

For the first time, Argonne’s scientists and engineers pinpointed engine designs for a given fuel using the Mira supercomputer at the heart of the Argonne Leadership Computing Facility (ALCF), a DOE Office of Science User Facility. With Mira’s supercomputing prowess, Argonne’s Virtual Engine Research Institute and Fuels Initiative (VERIFI) team simulated over 2,000 engine design combinations and “reduced design time from months to weeks,” said Sibendu Som, group leader and principal computational scientist at Argonne.

Cartography of the cosmos

Argonne researcher Salman Habib leads the “Computing the Sky at Extreme Scales” project or “ExaSky,” one of the first projects funded by the recently established Exascale Computing Project (ECP), a collaborative effort between DOE’s Office of Science and its National Nuclear Security Administration. From determining the initial cause of primordial fluctuations to measuring the sum of all neutrino masses, this project’s science objectives represent a laundry list of the biggest questions, mysteries and challenges currently confounding cosmologists.

ALCF supercomputers help address LHC’s growing computing needs

Argonne researchers are exploring the use of ALCF computing resources to process and analyze the massive amount of data generated by the ATLAS experiment at CERN’s Large Hadron Collider. Working with ALCF staff, the team is developing a pipeline that will allow ATLAS researchers to use Mira and Theta for the experiment’s intensive computing tasks—event generation, detector simulations, reconstruction, and analysis. Their work is demonstrating that DOE supercomputers provide a valuable tool for performing increasingly precise simulations, as well as calculations that are too intensive for traditional computing resources.

The sublime challenge of jet noise

Humans make a lot of noise. The riffs of heavy metal bands like Metallica and Kiss have soared to levels in the 130-decibel range, levels sure to lead to auditory damage.

  • Dye-sensitized solar panels

A window into solar

Buildings consume an estimated 40 percent of energy used in the United States – a burden that also represents a renewable energy opportunity. If researchers could turn windows and other structural components into solar energy cells, they could feed into a sustainable local power grid to heat, cool and light businesses and homes. Toward this goal, a research team at the University of Cambridge and the Argonne Leadership Computing Facility (ALCF), a Department of Energy Office of Science user facility, are seeking affordable, efficient chemical components of photovoltaic devices to embed in glass.

  • Detached eddy simulation of a vertical tail/rudder assembly with flow control

Extreme CFD: Fluid Dynamics Projects at ALCF

Kenneth Jansen is a professor from the University of Colorado Boulder with a flair for computational fluid dynamics (CFD). Currently he’s looking into advanced CFD as applied to large-scale simulations. In addition to his work for the University, Jansen is the P.I. of a team that is working under the auspices of the Argonne Leadership Computing Facility‘s Theta Early Science Program (Theta ESP).  He and his colleagues are tackling some of the most complex physics imaginable. They are honing in on the science associated with turbulent flows over aircraft control surfaces, such as the tail assembly and rudder.

  • A simulated sky image of galaxies

Big Bang – The Movie

In a new approach to enable scientific breakthroughs, researchers linked together supercomputers at the Argonne Leadership Computing Facility (ALCF) and at the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign (UI). This link enabled scientists to transfer massive amounts of data and to run two different types of demanding computations in a coordinated fashion – referred to technically as a workflow.
