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.

Argonne goes deep to crack cancer code

A cancer diagnosis is overwhelming, the treatment often complex and uncertain. Doctors have yet to understand how a specific cancer will affect an individual, and a drug that may hold promise for one patient, may not work for another.

ALCC program awards ALCF computing time to 24 projects

The U.S. Department of Energy’s (DOE’s) ASCR Leadership Computing Challenge (ALCC) has awarded 24 projects a total of 2.1 billion core-hours at the Argonne Leadership Computing Facility (ALCF). The one-year awards are set to begin July 1. Several of the 2017-2018 ALCC projects will be the first to run on the ALCF’s new 9.65 petaflops Intel-Cray supercomputer, Theta, when it opens to the full user community July 1.

ALCF workshop prepares researchers for Theta, Mira

More than 60 researchers attended the Argonne Leadership Computing Facility’s (ALCF) Computational Performance Workshop from May 2-5, 2017, for guidance on preparing and improving their codes for ALCF supercomputers, including Theta, the facility’s new 9.65 petaflops Intel-Cray system. With dedicated access to ALCF computing resources, the workshop provides an opportunity for attendees to work directly with staff and invited experts to test, debug, and optimize their applications on leadership-class supercomputers.

Fields and flows fire up cosmic accelerators

Researchers from the SLAC National Accelerator Laboratory are using Mira to conduct thorough investigations of plasma physics to discern the fundamental processes that accelerate particles. The answers could provide an understanding of how cosmic rays gain their energy and how similar acceleration mechanisms could be probed in the laboratory and used for practical applications.
