My SETI@home results

On this page I present some results of calculations which I carried out by means of the screensaver program of SETI@home. SETI@home is a scientific SETI project of the University of California, Berkeley. It uses the power of hundreds of thousands of Internet connected computers to analyze radio telescope data and to find a trace of a transmission of an extraterrestrial civilisation. An essential part of the SETI@home project is a free sreensaver program that is available on the SETI@home Page in Berkeley. This screensaver downloads and analyzes data received by the Arecibo Radio Telescope in Puerto Rico and sends the results back to Berkeley. It applies fast Fourier transforms and special algorithms which search for signals with a possibly non-natural origin. (Click here for details about signals for which SETI@home searches.) On May 28 2003 the number of SETI@home users reached the value 4.500.000. The classical SETI@home project ran until Dec 15 2005 and finished with a number of 5436301 users.

Since June 22 2004 a new version of SETI@home is available which is based on the platform BOINC for distributed computing, developed by the Seti@home team in Berkeley. BOINC can be used by many different, independent projects. In the course of 2004 several other BOINC-based distributed computing projects began to work. Since June 25 2004 I participate in the following BOINC-projects:
