    The Computing for Sustainable Water (CFSW) project focused on the Chesapeake Bay watershed in the United States. This is the largest watershed in the US and covers all or part of six states (Virginia, West Virginia, Maryland, Delaware, Pennsylvania, and New York) and Washington, D.C., the nation’s capital. The Bay has been under environmental pressure for many years. Previous efforts to address the problem have been unsuccessful. As a result, the size of the Bay’s anoxic region (dead zone) continues to affect the native blue crab (callinectes sapidus) population.

    he problem is largely a result of nutrient flow (nitrogen and phosphorous) into the Bay that occurs due to agricultural, industrial, and land development activities. Federal, state, and local agencies attempt to control nutrient flow through a set of incentives known as Best Management Practices (BMPs). Entities adopting BMPs typically receive payments. Each BMP is believed to be helpful in some way for controlling nutrient flow. However, the effectiveness of the various BMPs has not been studied on an appropriately large scale. Indeed, there is no clear scientific evidence for the effectiveness of some BMPs that have already been widely adopted.

    The Computing for Sustainable Water project conducted a set of large-scale simulation experiments of the impact of BMPs on nutrient flow into the Chesapeake Bay and the resulting environmental health of the Bay. Table 1 lists the 23 BMPs tested in this project. Initially, a simulation run with no BMPs was produced as a baseline case. Then each individual BMP was run separately and compared with the baseline. Table 2 shows the results of these statistical comparisons.

    Table 2. Statistical results comparing each BMP to a baseline (no-BMPs) simulation experiment.

    Student’s t-tests of individual BMPs compared to base case of no BMPs * = significant at α = 0.10; ** = significant at α = 0.05; *** = significant at α = 0.01

    These results identify several BMPs that are effective in reducing the corresponding nitrogen and phosphorous loads entering the Chesapeake Bay. In particular, BMPs 4, 7, and 23 are highly effective. These results are very informative for policymakers not only in the Chesapeake Bay watershed but globally as well, because many regions of the world experience similar problems and employ similar BMPs.

    In all, World Community Grid members facilitated over 19.1 million experiments. These include various combinations of BMPs to discover the possible effectiveness of combinations of BMPs. The analysis of these experiments continues for combinations of BMPs.

    We would like to once again express our gratitude to the World Community Grid community. A project of this size and scope simply would not have been possible without your help.

    Computing for Sustainable Water

    BOINC Announces a New Project at WCG: Computing for Sustainable Water 

    “The Computing for Sustainable Water (CFSW) project is one of three water-related projects selected to run on the IBM World Community Grid. This project evolved from the UVa Bay Game as a very detailed, simulation-only model of the Chesapeake Bay. Not a game, the CFSW model simulates over 34,000 spatial areas; 1,069 river and stream segments; and 4 million households over a 20-year period on a monthly basis. The model explores the potential outcomes of various practices (“Best Management Practices”) on the nutrient loads reaching and impacting Bay health.

    The CFSW project launched publicly on April 17, 2012 and is available for execution on the World Community Grid…

    The mission of the Computing for Sustainable Water project is to study the effects of human activity on a large watershed and gain deeper insights into what actions can lead to restoration, health and sustainability of this important water resource. The extensive computing power of World Community Grid will be used to perform millions of computer simulations to better understand the effects that result from a variety of human activity patterns in the Chesapeake Bay area. The researchers hope to be able to apply what is learned from this project across the globe to other regions which face challenges of sustainable water.

    Water is the most abundant resource on Earth, yet the world faces many challenging water-related problems. Among them is the management of its freshwater resources. More than 1.2 billion people lack access to clean, safe water. This problem is becoming more critical in the world as the proportion of people living in dense urban environments rises. The resulting demands for water contend with increasing human activities which degrade the quality of available water. A complex set of interrelated forces makes the problem difficult to address, much less to solve effectively via coordinated policy.

    The University of Virginia developed a participatory simulation model of the Chesapeake Bay, the UVa Bay Game® (www.virginia.edu/baygame), incorporating natural elements and human activity using game players representing crop farmers, land developers, watermen, and assorted regulators. The UVa Bay Game has been successful in providing a learning platform for conveying the issues of complex watershed behavior and management. But to better understand the complex natural and human dynamics at work in this complex system, a much more detailed simulation model was developed to run on World Community Grid. Each of many millions of computer simulations, using unique combinations of a wide variety of assumptions about the natural and human actions at play, will calculate the resulting effects on the watershed. Exploring these many results, the researchers expect to develop insight into how these assumptions affect the overall health of the Chesapeake Bay. With these insights, the researchers will be able to better inform policy makers and suggest how prudent actions can lead to water restoration and sustainability. The ultimate goal is to eventually apply this knowledge and the techniques learned with the Computing for Sustainable Water project to other watersheds around the world.”

    SETI@home The search for extraterrestrial intelligence. “SETI (Search for Extraterrestrial Intelligence) is a scientific area whose goal is to detect intelligent life outside Earth. One approach, known as radio SETI, uses radio telescopes to listen for narrow-bandwidth radio signals from space. Such signals are not known to occur naturally, so a detection would provide evidence of extraterrestrial technology.

    Radio telescope signals consist primarily of noise (from celestial sources and the receiver’s electronics) and man-made signals such as TV stations, radar, and satellites. Modern radio SETI projects analyze the data digitally. More computing power enables searches to cover greater frequency ranges with more sensitivity. Radio SETI, therefore, has an insatiable appetite for computing power.

    Previous radio SETI projects have used special-purpose supercomputers, located at the telescope, to do the bulk of the data analysis. In 1995, David Gedye proposed doing radio SETI using a virtual supercomputer composed of large numbers of Internet-connected computers, and he organized the SETI@home project to explore this idea. SETI@home was originally launched in May 1999.”

    SETI@home is the birthplace of BOINC software. Originally, it only ran in a screensaver when the computer on which it was installed was doing no other work. With the powerand memory available today, BOINC can run 24/7 without in any way interfering with other ongoing work.

    The famous SET@home screen saver, a beauteous thing to behold.

    einstein@home The search for pulsars. “Einstein@Home uses your computer’s idle time to search for weak astrophysical signals from spinning neutron stars (also called pulsars) using data from the LIGO gravitational-wave detectors, the Arecibo radio telescope, and the Fermi gamma-ray satellite. Einstein@Home volunteers have already discovered more than a dozen new neutron stars, and we hope to find many more in the future. Our long-term goal is to make the first direct detections of gravitational-wave emission from spinning neutron stars. Gravitational waves were predicted by Albert Einstein almost a century ago, but have never been directly detected. Such observations would open up a new window on the universe, and usher in a new era in astronomy.”

    MilkyWay@Home Milkyway@Home uses the BOINC platform to harness volunteered computing resources, creating a highly accurate three dimensional model of the Milky Way galaxy using data gathered by the Sloan Digital Sky Survey. This project enables research in both astroinformatics and computer science.”

    World Community Grid (WCG) World Community Grid is a special case at BOINC. WCG is part of the social initiative of IBM Corporation and the Smarter Planet. WCG has under its umbrella currently eleven disparate projects at globally wide ranging institutions and universities. Most projects relate to biological and medical subject matter. There are also projects for Clean Water and Clean Renewable Energy. WCG projects are treated respectively and respectably on their own at this blog. Watch for news.

    Rosetta@home “Rosetta@home needs your help to determine the 3-dimensional shapes of proteins in research that may ultimately lead to finding cures for some major human diseases. By running the Rosetta program on your computer while you don’t need it you will help us speed up and extend our research in ways we couldn’t possibly attempt without your help. You will also be helping our efforts at designing new proteins to fight diseases such as HIV, Malaria, Cancer, and Alzheimer’s….”

    GPUGrid.net “GPUGRID.net is a distributed computing infrastructure devoted to biomedical research. Thanks to the contribution of volunteers, GPUGRID scientists can perform molecular simulations to understand the function of proteins in health and disease.” GPUGrid is a special case in that all processor work done by the volunteers is GPU processing. There is no CPU processing, which is the more common processing. Other projects (Einstein, SETI, Milky Way) also feature GPU processing, but they offer CPU processing for those not able to do work on GPU’s.

    These projects are just the oldest and most prominent projects. There are many others from which you can choose.

    There are currently some 300,000 users with about 480,000 computers working on BOINC projects That is in a world of over one billion computers. We sure could use your help.
