LVEE Winter 2013

Berkeley Open Infrastructure for Network Computing (BOINC) is an open platform for distributed computing developed since February 2002 by University of California in Berkeley and licensed under LGPL. Initially it was built to support famous SETI@home project, aimed to search signals of extraterrestrial civilizations among the cosmic radio signals. Currently many projects run by known research centers from around the world uses BOINC. BOINC allows users having a computer and internet connectivity to participate in scientific projects. Thanks to University of California in Berkeley not only the research institutions gained "cheap" computing power, but also it allows to grow awareness of common internet users concerning the scientific problems, which must be dealt with.

Each year, the demand on computing resources of scientific and military institutions is increasing significantly. This process is noticeable almost from the very beginning of computers, which were quickly harnessed to complicated calculations. The symbol of advanced technology is TOP500 list. Updated twice a year, ranking presents 500 fastest computers on Earth.

An interesting alternative to centralized supercomputers is BOINC. BOINC1 is a system enabling use of personal computers for scientific research, and so, it can be considered as the the way to crowdsource scientific calculations. It allows to carry out calculations on a large scale incurring minimal costs associated with the purchase of equipment and its operation. In the case of BOINC infrastructure, as administrators we are forced to take care only of servers, which send computing tasks to the computers of individuals who have agreed to use their machines in his spare time to performed calculations for the good of science.

The user attaching to BOINC can choose one or several projects, in which he or she wishes to participate. The choice is very wide and covers many scientific fields from the mathematics and astrophysics to biochemistry. List of the best-known projects includes, among others, World Community Grid2. WCG is funded and managed by IBM. By providing the computing power of your PC in this project it contributes into, for example, the development of AIDS research, or into search of treatment for schistosomiasis. The LHC@Home3, which supports the project Large Hadron Collider (LHC), is also worth mentioning. One of the CERN department decided to use BOINC to simulate the behavior of particles orbiting in the accelerator which allows to study the stability of their trajectory. During the test on each machine simulates the most common trip 60 particles around the ring by 100 000 laps.

After registration, the BOINC and calculated in the selected project’s first tasks, you will receive points. They are to some extent paid for their input in the development of science.
Number of points owned by the user should reflect how much time user’s computers are dedicated to solving computational tasks. Fig. 1 presents the percentage of all points in the various fields of science. It is seen, that projects for Astronomy and Astrophysics are the most popular ones. Second place belongs to the queen of sciences, i.e. to mathematics. Distribution of points over nationalities is a special subject of interest. First position in terms of participation in BOINC belongs to Americans, of course, who have a significant advantage over Germans. The top five includes also England, Japan and France. This comparison is presented in Fig. 3. Fig. 2 presents a summary on used processors and operating systems. Linux operating system has a relatively large group of users here – up to 25.70%.

Certainly it can be concluded that BOINC platform as a solution is worth of attention even for those who have no connection with science.

With this kind of initiatives we can make something significant for our common civilization.
