IBM Enables Water Quality Predictions For Major Waterways in Partnership Between World Community Grid And University of Virginia

90 years of research collapsed into 12 months by using the power of two-million computers

CHARLOTTESVILLE, VA and ARMONK, N.Y. - 19 Apr 2012: IBM's World Community Grid and the University of Virginia today launched Computing for Sustainable Water, a project to simulate and predict the environmental and economic effects of agricultural, commercial, and industrial decisions over the next 20 years in and around the Chesapeake Bay, America's largest estuary. It can be adapted to study other bodies of water as well.

By harnessing the massive power of two-million computers -- a record number recently reached -- provided by close to 600,000 World Community Grid volunteers in 80 countries, scientists will conduct 1.3 million simulation experiments in just one year, a feat that would normally take 90 years.

Insights from the Computing for Sustainable Water project may help inform future public policy decisions for the Chesapeake Bay, but also for that of 400 major waterways and associated ecosystems worldwide -- half of which are under stress. It may also produce insights for water management practices to address the more than 1.2 billion people who currently lack access to clean, safe drinking water.

Individuals, businesses, and not-for-profits -- such as local governments, social service agencies, and schools -- can participate in University of Virginia's effort beginning today by downloading a free app from World Community Grid to their personal computers and similar non-mobile devices. The app enables volunteers' computers to perform calculations for the Computing for Sustainable Water project when their systems are not in use -- even between keystrokes. The process runs automatically, requires no time from volunteers, resists viruses, is environmentally friendly with little additional energy usage, and does not affect computer speeds.  

For the Computing for Sustainable Water project, the University of Virginia built a mathematical model that simulates the actions of 17.4 million people living in the 64,000 square-mile Chesapeake Bay watershed. It will predict the monthly and cumulative effects of agriculture, transportation, energy, and industry-related decisions made over the course of 20 years. Many assumptions will be taken under consideration in each scenario, such as the predicted proportion of homes connected to septic systems and wells, as compared to those connected to public sewer and water systems.  

The project builds on an earlier modeling effort by University of Virginia. Called the UVA Bay Game®, this simulation model primarily serves to raise awareness and educate people about the consequences of natural and man-made changes to the Chesapeake Bay watershed. Human game players simulate the decisions of farmers, land developers, watermen, and regulators. The results provide general insight into watershed behavior and management.

"After we complete a year of calculations, we expect to arrive at findings that could inform policy and stimulate individual behavior change in the Chesapeake Bay region and along its watershed," said Gerard Learmonth, a University of Virginia systems and information engineering professor who was instrumental in designing and building the Computing for Sustainable Water project. "What we learn from this project also could easily be extended to other regions of the world facing similar stresses on water quality. We are looking at whether or not various best management practices currently in use by governments will be effective in the long run for reducing the load of nitrogen, phosphorous, and sediment that is reaching the Chesapeake Bay from municipalities and agricultural areas and causing a decline in the health of the Bay. We hope that what we learn can not only help restore the health of the Bay, but also sustain it for future generations."

Scientists understand well what happens to water when specific changes in nature occur, but they can't as easily predict and anticipate how humans might influence those changes. To predict outcomes and unintended consequences of human-influenced development with any certainty, they need to simulate many possible cause-and-effect and "what-if "scenarios. To make timely progress, the complexity and amount of data involved requires fast and powerful computing -- an expensive proposition. World Community Grid, a kind of public supercomputer created and funded by IBM, provides the necessary computational power free of charge. 

"The University of Virginia's Computing for Sustainable Water project, proudly hosted on IBM's World Community Grid, is a terrific example of what happens when academia and the private sector team up to address critically important issues facing the environment and society," said Stanley S. Litow, IBM's vice president of Corporate Citizenship and Corporate Affairs, and president of IBM's International Foundation. "With two-million devices now powering World Community Grid, we're confident that the University of Virginia's project to explore the dynamics and decision affecting water quality will have more than enough resources at its disposal to shed to new light on how we all can be better stewards of the environment." 

World Community Grid hosts other clean-water projects, such as an effort at Tsinghua University in China to develop ways to filter, scrub, or treat polluted freshwater and seawater with less expense, complexity, and energy than current techniques. Other projects hosted by World Community Grid seek a faster way to cure disease (some of which are water-borne, such as schistosomiasis), find renewable energy materials, and develop healthier food staples.   

About IBM and World Community Grid  

World Community Grid is one of IBM's exciting philanthropic initiatives. Founded in 2004 and running on Berkeley Open Infrastructure for Network Computing (BOINC) software, it provides computational power to scientists who might not otherwise be able to afford the high speed computing they require for timely research. To date, 20 research projects have been hosted on World Community Grid, spinning off more than 30 peer-reviewed papers. Nine of the projects it has hosted have generated particularly promising results that are being further researched, or followed up with a second phase on World Community Grid. If it were a physical supercomputer, World Community Grid would be one of the world's 15 fastest such machines.
