Description/Abstract
High-value rare-event searching is arguably the most natural application of grid computing, where computational tasks are distributed to a large collection of clients (which comprise the computation grid) in such a way that clients are rewarded for performing tasks assigned to them. Although natural, rare-event searching presents significant challenges for a computation supervisor, who partitions and distributes the search space out to clients while contending with “lazy” clients, who don’t do all their tasks, and “hoarding ” clients, who don’t report rare events back to the supervisor. We provide schemes, based on a technique we call chaff injection, for efficiently performing uncheatable grid computing in the context of searching for high-value rare events in the presence of coalitions of lazy and hoarding clients.
