    What is BOINC

    BOINC is the next evolution in Distributed Computing. What's Distributed Computing you ask? Distributed Computing or DC for short, is the process of taking a large computational problem, dividing it up into little pieces and then giving those little pieces to hundreds of computers to solve each piece. Then all the completed pieces are returned to the originator where the data is reassembled to provide a result. DC has been around for some time.

    Even though Seti@home wasn't the first DC project, it exploded in popularity shortly after it's release in 1999. Anyone was able to download Seti@home to assist with the Search for Extra-Terrestrial Intelligence. The Seti@home client would request a small portion of data from Berkeley University's database of radio telescope recordings in the form of a Work Unit (WU). The client would then run complex calculations on this WU to see if there's any possibility of there being an radio broadcasts from deep space. The results would then be returned back to Berkeley. To reduce chance of error, the same WU is always sent to at least three different computers. This way there is verification that each computer came to the same conclusion.

    Seti@home revealed how powerful DC can be when combined with the Internet. This quickly lead to an influx of other DC projects that tried to solve everything from what's the largest prime number, to a cure for cancer. The problem was if you wanted to support multiple projects, you couldn't run them on the same computer at the same time without losing efficiency since they would battle for CPU time.

    Also, if you only did support one project, your computer would only be used if that one project was running. Large DC systems are very complex and hence they tend to have a lot of down time. This could leave potentially millions of computers without work during these outages. There has to be a better way.

    This is where the boys over at Berkeley came back into the picture. They too were aware of the limitations of the current DC systems so the developed the next evolution in DC technology. They developed Berkeley Open Infrastructure for Network Computing...BOINC.

    From a DC developer's side of things, BOINC is a common framework that can be use to quickly develop there systems by eliminating the need to develop a communication system, a user interface. Instead, developers can concentrate on the science.

    From a user's point of view, BOINC is a application that can be used to easily allow your computer to run multiple DC applications from a single common interface.

    If you want to think of Distributed Computing as retail stores, BOINC would be the mall. When store owner's choose to set up shop in a mall, they no longer need to worry about building a building, they can simply move right on into the mall. Shoppers no longer need to drive all over the city to find what they need. They can simply go to the mall and get everything they want. If one store happens to be out of stock on something, the consumer can easily walk to the next store.

    Points

    One of the fun aspects of running BOINC is the ability to collect points for the work your computer performs. This helps to quantify the work done by your computer as well as adds some friendly competitions among members and teams. Each project awards points slightly differently. But in general after your computer completes a single unit of work (Work Unit or WU for short), it will calculate how much it should deserve based on how long it took to process the WU while factoring in the benchmark scores. The WU's value is then uploaded along with the rest of the WU's results. Points are awarded after at least 2 or 3 (depending on the project) different computers upload the same results. This way both the work and the requested points are verified. The awarded points are then based on the combined values uploaded.

    ABC@home is a distributed computing project enabling a great search for so called abc-triples. The project is comparable in a way to GIMPS, another mathematical project. These abc-triples are positive integers a,b,c such that a+b=c, a < b < c, a,b,c have no common divisors and c > rad(abc), the so-called radical of abc. The ABC conjecture says that there are only finitely many a,b,c such that log(c)/log(rad(abc)) > h for any real h > 1. The ABC conjecture is currently one of the greatest open problems in mathematics. If it is proven to be true, a lot of other open problems can be answered directly from it.

    The aim of climateprediction.net is to investigate the approximations that have to be made in state-of-the-art climate models. By running the model thousands of times (a 'large ensemble') we hope to find out how the model responds to slight tweaks to these approximations - slight enough to not make the approximations any less realistic. This will allow us to improve our understanding of how sensitive our models are to small changes and also to things like changes in carbon dioxide and the sulphur cycle. This will allow us to explore how climate may change in the next century under a wide range of different scenarios. In the past estimates of climate change have had to be made using one or, at best, a very small ensemble (tens rather than thousands!) of model runs. By using your computers, we will be able to improve our understanding of, and confidence in, climate change predictions more than would ever be possible using the supercomputers currently available to scientists.

    The goal of Cosmology@Home is to search for the model that best describes our Universe and to find the range of models that agree with the available astronomical and particle physics data. In order to achieve this goal, participants in Cosmology@Home (i.e. you!) will compute the observable predictions of millions of theoretical models with different parameter combinations. We will use the results of your computations to compare all the available data with these models. In addition, the results from Cosmology@Home can help design future cosmological observations and experiments, and prepare for the analysis of future data sets.

    Description from their website.

    Einstein@Home is a program that uses your computer's idle time to search for spinning neutron stars (also called pulsars) using data from the LIGO and GEO gravitational wave detectors. Einstein@Home is a World Year of Physics 2005 project supported by the American Physical Society (APS) and by a number of international organizations.

    The Einstein@Home project searches for continuous wave sources of gravitational radiation via an "all-sky search". These sources may include gravitational radiation from pulsars. Einstein@Home may result in the first confirmed direct detection of a gravitational wave. A successful detection of gravitational waves would constitute a significant milestone in physics, as it would be the first detection of a previously unknown astronomical object by means of gravitational radiation alone.1

    Description from their website.

    The M4 Project is an effort to break 3 original Enigma messages with the help of distributed computing. The signals were intercepted in the North Atlantic in 1942 and are believed to be unbroken. Ralph Erskine has presented the intercepts in a letter to the journal Cryptologia. The signals were presumably enciphered with the four rotor Enigma M4 - hence the name of the project.

    The first message has been broken on February 20th, 2006. The signal in question is the second of the intercepts in Erskine's letter. You can read the raw server logs as well as an interpretation and translation.

    The second break has occurred on March 7th, 2006. The signal in question is the third of the intercepts in Erskine's letter. You can read the raw server logs as well as an interpretation and translation.

    The remaining message has not been broken yet, so you are still welcome to download the client and participate.

    Predictor@home is a world-community experiment and effort to use distributed world-wide-web volunteer resources to assemble a supercomputer able to predict protein structure from protein sequence. Our work is aimed at testing and evaluating new algorithms and methods of protein structure prediction. We recently performed such tests in the context of the Sixth Biannual CASP (Critical Assessment of Techniques for Protein Structure Prediction) experiment, and now need to continue this development and testing with applications to real biological targets. Our goal is to utilize these approaches together with the immense computer power that can be harnessed through the internet and volunteers all over the world (you!) to address critical biomedical questions of protein-related diseases.

    Description from their website.

    The amino acid sequence of a protein determines its three-dimensional structure, or 'fold'. Conversely, the three-dimensional structure is compatible with a large, but limited set of amino acid sequences. Enumerating the allowed sequences for a given fold is known as the 'inverse protein folding problem'. We are working to solve this problem for a large number of known protein folds (a representative subset: about 1500 folds). The most expensive step is to build a database of energy functions that describe all these structures. For each structure, we consider all possible sequences of amino acids. Surprisingly, this is computationally tractable, because our energy functions are sums over pairs of interactions. Once this is done, we can explore the space of amino acid sequences in a fast and efficient way, and retain the most favorable sequences. This large-scale mapping of protein sequence space will have applications for predicting protein structure and function, for understanding protein evolution, and for designing new proteins. By joining the project, you will help to build the database of energy functions and advance an important area of science with potential biomedical applications.
