ALCF contributes papers, posters, and more to SC14

With several Argonne authors, speakers, and panelists lined up to participate in SC14, the Argonne Leadership Computing Facility (ALCF), a DOE Office of Science User Facility, will have a strong presence at the high-performance computing community’s premier annual event, Nov. 16-21 in New Orleans.

SC is the leading venue for spotlighting original and innovative scientific and technical applications in high-performance computing, networking, storage, and analysis.

CiSE publishes first issue dedicated to Leadership Computing

Advances in Leadership Computing, the first of a two-part CiSE Special Issue on Leadership Computing, is now available online. In two consecutive publications, this special issue will explore nine projects that are using leadership systems to expand the frontiers of their fields.

  • Stress-corrosion cracking in silicates

Coding the cracks

According to the World Business Council for Sustainable Development, some five percent of total human energy consumption is currently spent breaking quartz and other silicates to retrieve much-needed metal ores. Silicates also are used widely in the manufacture of products as diverse as biomedical implants and semiconductors. But because these are brittle materials, they are prone to stress-corrosion cracking which can lead to costly damage and, eventually, product failure.

At the Department of Energy’s Argonne National Laboratory, a research team from King’s College London, led by British physicist James Kermode, has been working with the Argonne Leadership Computing Facility (ALCF) on a hybrid multiscale simulation program to virtually get inside this fracturing process.

Paul Messina Named Argonne Distinguished Fellow

High-performance computing pioneer Paul Messina has been named an Argonne National Laboratory Distinguished Fellow, the laboratory’s highest scientific and engineering rank. Comparable in stature to an endowed chair at a top-ranked university, the Argonne Distinguished Fellow title rank recognizes sustained outstanding scientific and engineering research and can also be associated with outstanding technical leadership of major, complex, high-priority projects.

ALCF storage upgrade aims for hands-off data management

The ALCF is in the midst of an innovative storage infrastructure upgrade aimed at reducing the amount of time users have to spend managing the massive amounts of data produced by its supercomputers.

For computational scientists, data management and I/O (input/output) efforts can include transferring files from the computer to storage and moving or retrieving data for analysis.

2014 Argonne Training Program on Extreme Scale Computing now underway

With the Argonne Training Program on Extreme Scale Computing (ATPESC) now underway in St. Charles, Illinois, we are pleased to provide access to videos of the presentations at last year’s program. Running through August 15, the ATPESC is organized and hosted by Argonne as a two-week “boot camp” for future users of leadership-class machines.

The intensive training program maintains a regimen of 10 hours’ worth of sessions each day, featuring lectures, panels, and hands-on exercises on using massively parallel computing architectures with hundreds of thousands of processor cores. Topics also address programming techniques and numerical algorithms that are effective in leading-edge, high-performance computing (

  • Ball and stick representation of salty water

Getting from H2O to hydrogen fuel

Producing hydrogen, a clean-burning alternative fuel, from water and sunlight almost sounds too good to be true. But that’s the idea behind photoelectrochemical (PEC) cells, which use solar energy to trigger a chemical reaction that splits water (H2O) into hydrogen (H2) and oxygen (O2) gases.

To help accelerate research and development efforts, Giulia Galli, a professor at the University of Chicago’s Institute for Molecular Engineering, is leading a project at the Argonne Leadership Computing Facility (ALCF) to advance the understanding of PEC water splitting.

  • 33 QMC Training Program participants

QMC workshop educates attendees on powerful tool to accelerate science

From July 14-18, the Argonne Leadership Computing Facility (ALCF), a DOE Office of Science user facility, hosted the Quantum Monte Carlo (QMC) Training Program to help grow the user base of this increasingly popular computational method for chemistry, materials science, and physics research.

QMC is one of the most accurate electronic structure methods, providing an important computational tool for solving many-body calculations for a broad range of electronic systems, from weakly bound molecules to strongly correlated solids. QMC is extremely scalable, but also requires significant computing power to run, making it a great fit for the ever-increasing power of today’s supercomputers.

Weathering the Flood of Big Data in Climate Research

Big Data, it seems, is everywhere, usually characterized as a Big Problem. But with the help of ALCF's computer scientist, Venkat Vishwanath, researchers at Lawrence Berkeley National Laboratory were able to move and analyze massive scientific datasets on Mira.
