  1. Is Anybody Out There?Embarrasingly Parallel Volunteer Computing Searching for ET and Transients with SETI@home Volunteers Dan Werthimer University of California, Berkeley http://seti.berkeley.edu

  2. SETI before FPGA’s

  3. NOTFUNDED

  4. NOTFUNDED

  5. NOTFUNDED

  6. Porno in space: FUNDED!

  7. First Radio SETI • Nikola Tesla (1899) • Announces “coherent signals from Mars” • Guglielmo Marconi (1920) • Strange signals from ET • Frank Drake (1960) • Project Ozma • one channel, 1420-1420.4 MHz

  8. Radio - Targeted Search Strategy Project Phoenix - Seti Institute Radio - Sky Survey Strategy Serendip, SETI@home - UC Berkeley Southern Serendip - Australia Meta II - Argentina Seti Italia - Bologna Optical - Targeted UC Berkeley - Pulse and Continuous Lick Observatory – Pulse Harvard – Pulse, Sky survey 2006

  9. Berkeley SETI Group David Anderson, Bob Bankay, Henry Chen, Jeff Cobb, Josh Von Korff, Eric Korpela, Matt Lebofsky, Andrew Siemion, Dan Werthimer, Shelley Wright NSF , NASA, Individual Donors Agilent, Fujitsu, HP, Intel, Sun, Xilinx

  10. UC Berkeley SETI Programs

  11. SERENDIP IV Photos Courtesy NAIC Arecibo Observatory, a facility of the NSF • 168M channels • 100 MHz Band centered on 1420 MHz

  12. (Naional Energy Research Scientific Computing Center)‏ Data storage: NERSC HPSS

  13. The SETI@home Client

  14. SETI@home Statistics TOTAL RATE

  15. Web site: 2 million hits/day 200,000 visitors/day(stats & games popular; science less popular)100,000 children, families(including congress members and their kids)> 7,000 schools

  16. Desired SKA Parameters • Wide bandwidth • 1 M beams • fat beams • short dwell times (~ 100 seconds)

  17. Gaussian Candidates

  18. Public Participation Supercomputing Group David Anderson, Rom Walton, SETI Group • aka Distributed Computing • aka “edge resource aggregation”)

  19. BOINC: NSF • Berkeley Open Infrastructure for Network Computing • General-purpose distributed computing framework. • Open source. • Will make distributed computing accessible to those who need it. (Starting from scratch is hard!)

  20. Projects • Astronomy • SETI@home (Berkeley) • Astropulse (Berkeley) • Einstein@home: gravitational pulsar search (Caltech,…) • PlanetQuest (SETI Institute) • Stardust@home (Berkeley, Univ. Washinton,…) • Earth science • Climateprediction.net (Oxford) • Biology/Medicine • Folding@home, Predictor@home (Stanford, Scripts) • FightAIDSathome: virtual drug discovery • Physics • LHC@home (Cern) • Other • Web indexing/search • Internet Resource mapping (UC Berkeley)

  21. Rosetta Screensaver

  22. Where's the computing power? your computers home PCs academic business • 2010: 1 billion Internet-connected PCs • 55% privately owned • If 100M participate: • 100 PetaFLOPs, 1 Exabyte (10^18) storage
