SUPERCOMPUTERS TO BRING NCAR SIGNIFICANTLY CLOSER TO COMPLETE WEATHER MODEL

 BOULDER, Colo., June 1 /PRNewswire/ -- The National Center for Atmospheric Research (NCAR) announced activation of supercomputers that will provide the foundation to answer critical questions about global warming and greenhouse gases.
 The heterogeneous supercomputing union will be comprised of a massively parallel processing (MPP) supercomputer, the Connection Machine, CM-5, from Massachusetts-based Thinking Machines Corporation, and a vector supercomputer, the Cray-3 from the Colorado Springs-based Cray Computer, Inc (NASDAQ-NMS: CRAY).
 As the principal center in research and modeling of the earth's atmosphere and oceans for the University Corporation on Atmospheric Research, NCAR expects the supercomputers will advance Climate Modeling Research.
 "The goal of this initiative is to produce modeling capability that accommodates higher resolution, more sophisticated physics, and a computing system that facilitates incremental and cost-effective use of MPP technology," said Bill Buzbee, scientific computing division director at NCAR.
 One of the most data intensive and complicated applications, climate models are well suited to be distributed among multiple processors. A complete climate model, one which realistically couples atmospheric and ocean systems, requires enormous amounts of computing power. In concept, such a model would incorporate every atmospheric and oceanic dynamic on earth -- including winds, ocean currents, sea surface temperatures, land masses, topography, vegetation, among others -- enabling scientists to make a significant advance in their understanding of the earth's climate.
 "We plan to put a lot of effort into supporting NCAR's pursuit of its climate model research," said Danny Hillis, founding scientist at Thinking Machines. "Accurate global climate modeling is important to our future, not just Thinking Machine's future, the future of planet Earth."
 The CM-5 supercomputer recently passed acceptance testing at NCAR with 100 percent uptime. Many NCAR users are anxious to get hands-on experience with MPP technology, and training courses for the CM-5 are set to begin in June, the Cray 3 installed in May, is presently undergoing acceptance testing.
 Thinking Machines Corporation is the world leader in the design, development and manufacture of highly parallel supercomputers. The company's Connection Machine(a) (CM-5) system is the most powerful supercomputer in the world. Thinking Machines, privately held, has offices worldwide.
 With a budget of about $90 million and a staff of roughly 800, the National Center for Atmospheric Research focuses on the research and modeling of atmospheric, oceanographic and related systems. NCAR is funded by the National Science Foundation.
