Scientists at NCAR and across the country will use the new system to accelerate research into climate change, including future patterns of precipitation and drought around the world, changes to agriculture and growing seasons, and the complex influence of global warming on hurricanes. Researchers also will use it to improve weather forecasting models so society can better anticipate where and when dangerous storms may strike.
Named "bluefire," the new supercomputer has a peak speed of more than 76 teraflops (76 trillion floating-point operations per second). When fully operational, it is expected to rank among the 25 most powerful supercomputers in the world and will more than triple NCAR's sustained computing capacity.
"Bluefire is on the leading edge of high-performance computing technology," says Tom Bettge, director of operations and services for NCAR's Computational and Information Systems Laboratory. "Increasingly fast machines are vital to research into such areas as climate change and the formation of hurricanes and other severe storms. Scientists will be able to conduct breakthrough calculations, study vital problems at much higher resolution and complexity, and get results more quickly than before."
Researchers will rely on bluefire to generate the climate simulations necessary for the next report on global warming by the Intergovernmental Panel on Climate Change (IPCC), which conducts detailed assessments under the auspices of the United Nations. The IPCC was a recipient of the 2007 Nobel Peace Prize.
"NCAR has a well-deserved reputation for excellence in deploying supercomputing resources to address really difficult challenges," says Dave Turek, vice president of deep computing at IBM. "Bluefire will substantially expand the organization's ability to investigate climate change, severe weather events, and other important subjects."
Bluefire by the numbers
Bluefire is the second phase of a system called the Integrated Computing Environment for Scientific Simulation (ICESS) at NCAR. After undergoing acceptance testing, it will begin full-scale operations in August. Bluefire, which replaces three supercomputers with an aggregate peak speed of 20 teraflops, will provide supercomputing support for researchers at NCAR and other organizations through 2011.
An IBM Power 575 supercomputer, bluefire houses the new POWER6 microprocessor, which has a clock speed of 4.7 gigahertz. The system consists of 4,064 processors, 12 terabytes of memory, and 150 terabytes of FAStT DS4800 disk storage.
Bluefire relies on a unique, water-based cooling system that is 33 percent more energy efficient than traditional air-cooled systems. Heat is removed from the electronics by water-chilled copper plates mounted in direct contact with each POWER6 microprocessor chip. As a result of this water-cooled system and POWER6 efficiencies, bluefire is three times more energy efficient per rack than its predecessor.
"We're especially pleased that bluefire provides dramatically increased performance with much greater energy efficiency," Bettge says.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
