IBM's World Community Grid reveals three new research projects on as many continents |
|
|
IBM's World Community Grid, a worldwide network of PC owners helping scientists solve humanitarian challenges, has announced several computing projects aimed at developing techniques to produce cleaner and safer water, an increasingly scarce commodity eluding at least 1.2 billion people worldwide.  One initiative will simulate how human behaviors and ecosystem processes relate to one another in watersheds such as the Chesapeake Bay. Other projects will explore advanced water filtering techniques and seek cures for a water-borne disease. To speed up these projects while lowering the cost and increasing their precision, scientists will harness the IBM-supported World Community Grid to perform online simulations, crunch numbers and pose hypothetical scenarios. Processing power for all that computing will come from a grid of 1.5 million PCs from 600,000 volunteers around the world, from otherwise “underutilized” machines. IBM said scientists also use World Community Grid -- equivalent to one of the world's fastest supercomputers -- to engineer cleaner energy, cure disease and produce healthier food staples. People around the world donate time on their computers for humanitarian projects by registering on www.worldcommunitygrid.org, and installing a free, unobtrusive and secure software program on their personal computers running either Linux, Microsoft Windows or Mac OS. When idle or between keystrokes on a lightweight task, the PCs request data from World Community Grid's server, which runs Berkeley Open Infrastructure for Network Computing (BOINC) software, maintained at Berkeley University and supported by the National Science Foundation. The first project is called the University of Virginia Watershed Sustainability Project, which will use World Community Grid to power its "UVa Bay Game/Analytics" project, which models the effects of agricultural, commercial and industrial decisions on the Chesapeake Bay. This waterway is a vital estuary on the East Coast of the United States, stretching 64,000 square miles with 11,600 miles of tidal shoreline, and home to nearly 17 million people. It will simulate and analyze the results of choices made by the sometimes-competing interests of fishermen, farmers, real estate developers, power plant designers, conservationists, forestry experts and urban planners. Better understanding the potential outcomes of complex, intersecting decisions can help society manage the watershed more effectively. Another new water-related project, called "Computing For Clean Water," is looking to produce more efficient and effective water filtering, and is now getting underway at Tsinghua University's newly launched Centre for Novel Multidisciplinary Mechanics in China, IBM said. The idea is to develop ways to filter and scrub polluted water, as well as convert saltwater into drinkable freshwater, with less expense, complexity, and energy than current techniques. The effort seeks to reduce the pressure and energy required to force water through microscopic, nanometer-sized pores in tubes made of carbon, whose tiny holes prevent harmful organic material from being transmitted. For this study, scientists will need to produce millions of computer simulations to model how water molecules interact with one another and against the walls of these carbon nanotubes. A third initiative, to be run on World Community Grid out of Brazil's Inforium Bioinformatics, in collaboration with FIOCRUZ-Minas, is seeking to cure schistosomiasis, a significant, parasite-based disease prevalent in tropical regions that is incubated and transmitted via foul water. The World Health Organization lists this disease as highly necessary to control, as it kills between 11,000 to 200,000 people every year and infects about 210 million individuals in 76 countries. It takes a severe toll on undeveloped countries, causing about 1.7 million disability-adjusted life-years of burden annually. While the drug Praziquantel has been largely effective in treating the disease for more than 25 years, drug-resistant strains are of concern. Researchers will seek to identify human protein targets for possible new drug treatments, and will use the World Community Grid to screen up to 13 million compounds found in the zinc.docking.org database against 180 protein structures involved with the parasite. IBM says that while this may not lead to new drugs immediately, it will greatly augment the study of this disease by scientists around the world. IBM has contributed server hardware, software, technical services and expertise to build the infrastructure for World Community Grid and provides free hosting, maintenance and support. |
