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.

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.

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.

Widening horizons for high schoolers with code

Last month, the U.S. Department of Energy’s (DOE) Argonne National Laboratory hosted a five-day Coding Camp for more than two dozen high school juniors and seniors, teaching new programming skills and how computer science is an integral part of an Argonne researcher’s life. The coding camp started three years ago from a vision of Mike Papka, deputy associate lab director and director of the Argonne Leadership Computing Facility (ALCF), to encourage and inspire youth to learn about computer science before they reach college.

Big Data meets big healthcare for veterans

Argonne’s extensive track record of successes with big data and big computers make it the quintessential partner of this multi-faceted research team to improve healthcare for millions of veterans, advance supercomputing and solve some of the nation’s biggest scientific challenges. A team led by Argonne’s Rick Stevens, associate laboratory director for Computing, Environment and Life Sciences, was instrumental in moving the effort from concept to reality.
