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

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
