Summary:
The Argonne Leadership Computing Facility has run over two billion processor-hours of computations at a mind-boggling speed of over 557 trillion calculations a second as it enables scientists and engineers to conduct cutting-edge research in just weeks or months rather than years.

FULL STORY

Above, the project that pushed the ACLF over two billion processor-hours: a visualization of Rayleigh-Taylor instability, which is the result of the mixing of two fluids at different densities. The heavy fluid (top) is accelerated by the light fluid (bottom), yielding bubbles of light fluid and spikes of heavy fluid, each penetrating into the other fluid, followed by the development of a chaotic mixing layer. Gravity is going down in the plot. Accurate simulation of the turbulent mixing of two fluids is a long-standing challenge.

The Argonne Leadership Computing Facility (ALCF), located at the U.S. Department of Energy's (DOE) Argonne National Laboratory, has run over two billion processor-hours of computations at a mind-boggling speed of over 557 trillion calculations a second as it enables scientists and engineers to conduct cutting-edge research in just weeks or months rather than years.

"The ALCF is dedicated to enabling breakthrough science -- science that will change our world," said Pete Beckman, director of the ALCF. "From understanding the basic building blocks of nature to fueling industry and driving innovation, the power of supercomputers touches all of our lives."

No longer mere tools in the search for technical knowledge, supercomputers have become increasingly essential to almost every aspect of science and engineering. For example, researchers are using Argonne's supercomputer to:

  • Model the molecular basis of Parkinson's disease to develop new treatments
  • Assess the impacts of regional climate change
  • Design technologies to reduce aerodynamic noise and cut carbon emissions
  • Gain insight into dangerous heart rhythm disorders
  • Design new materials required for lithium-air batteries

A "processor-hour" represents a single computer processor running for one full hour. In May of 2010, researchers from SUNY at Stony Brook were studying computational fluid dynamics when the ALCF reached the two billion processor-hour mark.

The ALCF is home to the IBM Blue Gene/P Intrepid, one of the fastest supercomputers in the world for open science. Intrepid features more than 160,000 processors and more than 80 terabytes of memory. Intrepid boasts a peak performance of 557 teraflops, but despite its power, the energy-efficient system uses about one-third as much electricity as a machine of comparable size built with more conventional parts.
