The Berkeley Open Infrastructure for Network Computing (BOINC) is an open-source platform that enables researchers to run distributed computing projects on thousands of public PCs. BOINC was developed by the team behind SETI@home, the screensaver programme that analyses radioastronomical data for signs of extraterrestrial intelligence, which has been downloaded on more than 5 million computers. Since BOINC's launch two years ago, several scientific projects have implemented it, attracting thousands of 'PC volunteers', CERN's LHC@home project being one of these. This seminar will review two of these projects, both from the point of view of the scientific computing challenges they involve, and the scientific results they aim to produce. The seminar is in two parts:

  1. Einstein@Home is a project developed to search data from the Laser Interferometer Gravitational wave Observatory (LIGO) in the US and from the GEO 600 gravitational wave observatory in Germany for signals coming from extremely dense, rapidly rotating stars. Such sources are believed to be either quark stars or neutron stars, and a subclass of these are already observed by conventional means as pulsars or X-ray emitting celestial objects. Einstein@home is an official project of the Year of Physics.
  2. climateprediction.net aims to investigate the approximations that have to be made in state-of-the-art climate models by running such models thousands of times under a range of approximations. This will help understand how sensitive different models are to small changes in, for example, the carbon dioxide and the sulphur cycle. This will contribute to exploring how climate may change in the next century under a wide range of different scenarios.
