  1. The art of Distributed Computing

  2. What is it? • Multiple computers can help on larger project • Each computer gets work units • Usually, 2 or 3 computers get same work unit for redundancy. • Results reported back

  3. How does it work? • Install distributed computing client on your PC • Configure how much CPU/RAM/HD space it is allowed • Subscribe to at least one project • Automatically download work units and report back when finished

  4. What are the advantages? • Enormous resources available • DC Record 1256 TFLOPS from 261856 CPUs • BlueGene/L Record 478.2 (596.4) TFLOPS • Fault-tolerant • Open • Scalable

  5. What are the drawbacks? For the developer • Program must be segmented • A few nodes must be reachable For the participant • Computer may be prone to overheating • Minimal CPU/RAM/HD usage

  6. What projects are available? • Folding@home • Protein Folding • LHC@home • Calibrating the LHC • Search for the Higgs-Boson • IBM World Community Grid • FightAIDS@Home • Help Conquer Cancer • SETI@home • Search for signals from ET

  7. Can I help? • Download BOINC • http://boinc.berkeley.edu/ • Join one of the many communities • Pick an interesting project and donate unused CPU cycles

  8. Questions?
