The Blue Gene/P - known as Intrepid and located at the Argonne Leadership Computing Facility (ALCF) - also ranked third fastest overall. Both rankings represent the first time an Argonne-based supercomputing system has ranked in the top five of the industry's definitive list of supercomputers.

The Blue Gene/P has a peak-performance of 557 Teraflops (put in other terms, 557 million calculations per second). Intrepid achieved a speed of 450.3 Teraflops on the Linpack application used to measure speed for the TOP500 rankings.

"Intrepid's speed and power reflect the DOE Office of Science's determined effort to provide the research and development community with powerful tools that enable them to make innovative and high-impact science and engineering breakthroughs", stated Rick Stevens, associate laboratory director for computing, environmental and life sciences at Argonne.

"The ALCF and Intrepid have only just begun to have a meaningful impact on scientific research", Rick Stevens stated. "In addition, continued expansion of ALCF computing resources will not only be instrumental in addressing critical scientific research challenges related to climate change, energy, health and our basic understanding of the world, but in the future will transform and advance how science research and engineering experiments are conducted and attract social sciences research projects, as well."

"Scientists and society are already benefiting from ALCF resources", stated Peter Beckman, ALCF acting director. "For example, ALCF's Blue Gene resources have allowed researchers to make major strides in evaluating the molecular and environmental features that may lead to the clinical diagnosis of Parkinson's disease and Lewy body dementia, as well as to simulate materials and designs that are important to the safe and reliable use of nuclear energy plants."
