1. All the computers in the world (~1 billion) BOINC: high-level goal Computational science biology, medicine Earth sciences, physics, astronomy, math, A.I.,... Volunteer computing

2. BOINC: basic technology ● PC owner – Install BOINC client – Find projects – Attach, set allocations ● Scientist – Set up server – Port application – Add web content – Voila! Foobar@home http://boinc.berkeley.edu

3. Where we're at 20 projects 450,000 compute rs

4. Computing power

5. Ideas and work in progress ● More participants – Branded versions (BBC, Discovery Channel, Seed) – Bundling (Debian; MS? Dell?) ● More scientists – Project hosting ● World Community Grid (IBM) ● Africa@home (CERN) Africa@home ● University-sponsored – Computing portals with widely-used apps ● NIH@home

6. More ideas and work in progress ● How do people discover projects? – “Account manager” web sites, e.g. GridRepublic http://gridrepublic.org http://gridrepublic.org ● How to encourage churn? – “Science stock exchange”: encourage discovery of good new projects ● How to influence PC purchase decisions – Credit system: give points for RAM, disk, network usage, availability, etc.; reflect project needs
