  • Corrosion

The Core of Corrosion

Anyone who has ever owned a car in a snowy town – or a boat in a salty sea – can tell you just how expensive corrosion can be. One of the world’s most common and costly chemical reactions, corrosion happens frequently at the boundaries between water and metal surfaces. In the past, the process of corrosion has mostly been studied from the metal side of the equation.

However, in a new study, scientists at the Center for Nanoscale Materials at the U.S. Department of Energy’s Argonne National Laboratory investigated the problem from the other side, looking at the dynamics of water containing dissolved ions located in the regions near a metal surface.

  • Intrepid, the ALCF's Blue Gene/P supercomputer

Passing the Torch from Intrepid to Mira

Much like personal computers, the average lifespan of a supercomputer is four to five years. In 2013, Intrepid, the Argonne Leadership Computing Facility’s (ALCF) IBM Blue Gene/P supercomputer, hit the five-year mark, ending an impressive run of innovative computational research.

Ranked as the third fastest computer in the world when it debuted in 2008, Intrepid enabled researchers to accelerate studies of everything from advanced battery materials and climate models to supernovae and Parkinson’s disease. The 557-teraflops system was decommissioned on Dec. 31, 2013, but its legacy lives on in many of the ALCF’s ongoing research projects.

  • GLEAN - strong scaling performance

GLEANing Scientific Insights More Quickly

Researchers at the Argonne Leadership Computing Facility (ALCF) are developing a software tool, called GLEAN, to help users optimize data movement between the compute, analysis, and storage resources of high-performance computing systems. This speeds the computer’s ability to read and write data, also known as input/output (I/O) performance, giving researchers a faster path to scientific insights.
