MINNEAPOLIS SYMPOSIUM TO FOCUS ON SUPERCOMPUTING APPLICATIONS IN ENVIRONMENTAL STUDIES

 MINNEAPOLIS SYMPOSIUM TO FOCUS ON SUPERCOMPUTING
 APPLICATIONS IN ENVIRONMENTAL STUDIES
 Program Designed to Improve
 Accuracy of Numerical Modeling
 EAGAN, Minn., July 6 /PRNewswire/ -- On the heels of the Earth Summit held last month in Rio de Janeiro, more than 150 of the world's top environmental researchers and mathematicians will come together beginning today at the University of Minnesota for a four-week symposium created to help increase the accuracy of environmental computer models for research into such areas as acid rain, urban air pollution, and the greenhouse effect.
 The program, called the Summer Program on Mathematical, Computational and Statistical Analyses in Environmental Studies, was organized by the Institute for Mathematics and its Applications (IMA), Minneapolis, with funding support from Cray Research, Inc., the leading provider of high-performance computing systems (supercomputers) worldwide. Established on the University of Minnesota campus in 1982 with funds from the National Science Foundation (NSF), IMA conducts activities to improve communication between mathematicians and other scientists in academia, government research labs and industry. Many of the IMA programs are targeted to industrial use of mathematics; Cray Research belongs to a consortium of 13 industries and 25 universities that support the IMA and its programming.
 Avner Friedman, director of the IMA, said the July program marks the first time the mathematics community has developed a program focused exclusively on environmental topics. "Mathematical modeling and large- scale data collection and analysis are at the core of all environmental studies," said Friedman. "This program is designed to provide a much needed interdisciplinary forum for joint exploration of recent advances in and application of mathematical models for studying such problems as ozone depletion, global climate change, acid rain, pollution dispersion and hazardous waste disposal. We will bring together the environmental researchers who understand the problems with the people who understand the core math and its recent advances to attack these problems."
 David Blaskovich, director of environmental systems marketing for Cray Research, said that Cray Research supercomputers have been used in environmental research for more than 15 years. Worldwide, 21 Cray Research systems are used in environmental applications ranging from weather forecasting to modeling global climate change.
 "Environmental problems involve extremely complex physical, chemical and biological interactions that can be unified through mathematical analysis," said Dave Blaskovich, director of environmental systems marketing for Cray Research. "The key limiting factors in environmental research are accurate and accessible data, simulation capability (numerical models) and supercomputing capacity. Our support for this symposium will help advance the development of numerical models to attack larger and more complex environmental problems." Blaskovich noted that supercomputer-based simulation has become the prevailing tool for identifying, assessing and resolving many types of environmental problems. Increasingly, well-informed environmental policy will be based on information generated by simulations run on supercomputers.
 Blaskovich noted that among the organizers and participants in the IMA program are several researcher who use Cray Research systems in their work. For example, Dr. Gregory McRae, a chemical engineer at Carnegie Mellon University, is using Cray Research supercomputers at the Pittsburgh Supercomputer Center to develop more effective air quality control strategies for optimal legislative controls on pollution emission. His modeling of the L.A. basin area influenced legislation controls on pollutants emitted from automobiles, other vehicles, and even lawn mowers in California. His model is also being used to investigate air pollution in Mexico City.
 Dr. Mary Wheeler of Rice University, chairperson for the IMA program, does hydrology studies on Cray Research systems. Dr. Julius Chang, an EPA-funded researcher from the State University of New York- Albany, uses Cray Research systems located on the National Science Foundation network to develop and enhance the U.S. regional acid rain model. His model, considered the premier acid rain model in the world, is being adapted for regional acid rain research in Asia and Europe.
 "Our sponsorship of the IMA program continues Cray Research's active support for supercomputing-based environmental research," said Blaskovich. He noted that in September 1991, Cray Research organized and hosted a symposium in Salzburg, Austria, at which leading environmental experts discussed advances in multidisciplinary environmental models -- those that include meteorology, chemistry and oceanography -- for supercomputers.
 Cray Research creates the most powerful, highest-quality computational tools for solving the world's most challenging scientific and industrial problems.
