Einstein@Home is a volunteer distributed computing project that searches through data from the LIGO detectors for evidence of continuous gravitational-wave sources, which are expected from objects such as rapidly spinning non-axisymmetric neutron stars. A sister project examines radio telescope data from the Arecibo Observatory, searching for radio pulsars. Running on the Berkeley Open Infrastructure for Network Computing (BOINC) software platform, Einstein@Home is hosted by the University of Wisconsin–Milwaukee and the Max Planck Institute for Gravitational Physics (Albert Einstein Institute, Hannover, Germany). Its director is Bruce Allen. On August 12, 2010, the first discovery by Einstein@Home of a previously undetected radio pulsar J2007+2722, found in data from the Arecibo Observatory, was published in ''Science''.〔 The project had discovered 49 pulsars as of December 2014. Einstein@Home is free software released under the GNU General Public License, version 2.〔(Einstein@Home application source code and license )〕 == Introduction == The project was officially launched on 19 February 2005 as part of the American Physical Society's contribution to the World Year of Physics 2005 event. It uses the power of volunteer-driven distributed computing in solving the computationally intensive problem of analyzing a large volume of data. Such an approach was pioneered by the SETI@home project, which is designed to look for signs of extraterrestrial life by analyzing radio wave data. Einstein@Home runs through the same software platform as SETI@home, the Berkeley Open Infrastructure for Network Computing (BOINC). As of August 2012, over 300,000 volunteers in 221 countries had participated in the project, making it the third-most-popular BOINC application. Users regularly contribute about 1.005 petaFLOPS of computational power, which would rank Einstein@Home among the top 20 on the TOP500 list of supercomputers.〔(Server status )〕
