A brief history of volunteer computing
Applications
Platforms
1995 2005distributed.net, GIMPS
SETI@home, Folding@home
Commercial: Entropia, United Devices, ...
BOINC
Predictor@home,WCG, Einstein, Rosetta, ...
20052000 2008
Academic: Bayanihan, Javelin, ...
Applications
Volunteer computing today
Participation 500K people, 1M computers 5 PetaFLOPS (100x cheaper than clusters)
Scientific impact molecular simulation climate modeling astronomy
Performance potential 1 ExaFLOP = 4M GPUs mobile devices: lowest watts/FLOPS
BOINC: middleware for volunteer computing client, server, web http://boinc.berkeley.edu
Handling diversity
Cluster/Grid/Cloud Volunteer
BOINC mechanisms:adaptive replicationhomogeneous replicationhost punishmentjob size matching
The volunteer computing ecosystem Goals:
give resources to important, productive projects large, dynamic set of projects scientifically informed public
Ideas: “mutual funds” (e.g., American Cancer
Society) futures market
