  • 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.

  • 2018 ALCF Computational Performance Workshop

ALCF hands-on workshop connects researchers with HPC experts

For three days this May, more than 40 researchers visited the Argonne Leadership Computing Facility (ALCF), a U.S. Department of Energy (DOE) Office of Science User Facility, to improve the performance of their computational science codes by working alongside the experts who know the facility’s supercomputers best. With extensive hands-on sessions, dedicated access to ALCF systems, and introductions to the tools, services, and computing resources available to facility users, the annual ALCF Computational Performance Workshop is designed to accelerate researchers’ efforts to test, debug, and optimize their codes on leadership-class systems.

Extending high-accuracy quantum chemistry calculations with HPC

Researchers at the Argonne National Laboratory recently performed the largest, and most accurate calculation of a metal organic framework system that was ever done. What made this possible was the Theta supercomputer at the Argonne Leadership Computing Facility (ALCF) with the latest generation processors that incorporated extra memory on the chip to aid in memory intensive calculations.

  • Atomistic simulations of the chemical mechanism leading to reduced friction

Argonne researchers develop new self-generating lubricant

Argonne researchers coupled laboratory experiments and large-scale molecular dynamics simulations to develop a new lubricant material that last much longer than other solid lubricants. Using Mira, the team performed atomistic simulations that revealed molecular insights into a mechanical stress-induced tribochemical reaction that led to superlubricity.

  • E3SM

E3SM provides powerful, new Earth system model for supercomputers

The Earth — with its myriad shifting atmospheric, oceanic, land, and ice components — presents an extraordinarily complex system to simulate using computer models. But a new Earth modeling system, the Energy Exascale Earth System Model (E3SM), is now able to capture and simulate all these components together. Released on April 23, after four years of development, E3SM features weather-scale resolution — i.e., enough detail to capture fronts, storms, and hurricanes — and uses advanced computers to simulate aspects of the Earth’s variability. The system can help researchers anticipate decadal-scale changes that could influence the U.S. energy sector in years to come.
