In search of a signal

A research team from Argonne National Laboratory and McGill University is performing simulations at the Argonne Leadership Computing Facility (ALCF), a U.S. Department of Energy (DOE) Office of Science User Facility, to construct cosmological maps that will help improve the analysis of data from two of the world’s most powerful astronomical instruments, the Dark Energy Survey and the South Pole Telescope. The enhanced maps will allow scientists to better understand the gravitational forces at work on large-scale structures in the universe—and by extension some of cosmology’s greatest mysteries such as dark energy and dark matter.

Argonne discovery yields self-healing diamond-like carbon

Large-scale reactive molecular dynamics simulations carried out on the Mira supercomputer at the Argonne Leadership Computing Facility, along with experiments conducted by researchers in Argonne’s Energy Systems Division, enabled the design of a “self-healing,” anti-wear coating that dramatically reduces friction and related degradation in engines and moving machinery. Now, the computational work advanced for this purpose is being used to identify the friction-fighting potential of other catalysts.

  • ATPESC 2015

Argonne’s annual HPC training program now underway

The Argonne Training Program on Extreme-Scale Computing (ATPESC), a two-week “boot camp” introducing a group of 65 participants on how to effectively use the world’s most powerful supercomputers, is set to begin on July 31.

This pioneering program, now in its fourth year, aims to educate the next generation of researchers on all aspects of high-performance computing (HPC), including programming techniques, advanced numerical algorithms, and current and emerging computing architectures.

Scientists optimize defects for better superconducting effects

In a new study, researchers at Argonne National Laboratory have developed a rational approach to optimize the arrangement of defects to enhance the current-carrying capacity of commercial high-temperature superconducting wires. The researchers used a synergistic approach that combined experiments with computer simulations carried out at the Argonne Leadership Computing Facility.
