  • Turbulent envelope of a luminous blue variable star

Superstars’ secrets

Although massive stars are important to understanding astrophysics, the largest ones – at least 20 times the sun’s mass – are rare and highly variable. A team of astrophysicts is using ALCF computing resources to model the variability in three dimensions across an entire massive star. They’ve published the initial results from these large-scale simulations – linking brightness changes in massive stars with temperature fluctuations on their surfaces – in the Sept. 27 issue of the journal Nature.

  • Simulated data modeled for the ATLAS detector

Argonne team brings leadership computing to CERN’s Large Hadron Collider

A team of collaborators from the U.S. Department of Energy’s (DOE) Argonne National Laboratory is exploring the use of ALCF supercomputers to help meet the growing computing demands of the ATLAS experiment at CERN’s Large Hadron Collider. The team has used ALCF computing resources for multiple projects aimed at expediting the processing and simulation of data produced by the ATLAS experiment.

ALCF simulations shed light on technique to alter materials properties

Researchers from the University of Southern California are using ALCF computing resources to observe how changes in the atomic structure of a semiconductor material might convert it to metal. The ability to do so could drastically reduce the time and cost required to manufacture semiconductors—key components in most electronic devices—and extend their use to more novel applications, like flexible electronics.

  • CodeGirls@Argonne camp

Teaching the programmers of tomorrow

The CodeGirls@Argonne camp is designed to immerse young girls in computer science before they enter high school and introduce them to potential career paths in science, technology, engineering, and mathematics (STEM). Staff members from the Argonne Leadership Computing Facility (ALCF) are among the volunteers who help the CodeGirls event fulfill its mission of bringing computer science to a population that’s often underrepresented in the field.
