Locust-a brokerage system for accessing idle resources for Web-Computing

In this paper we present a brokerage system for making idle cpu resources of anonymous users of the World Wide Web accessible for distributed Web-Computing. The Locust (LOw cost Computing Utilizing Skimmed idle Time) Broker collects and remarkets the aggregated resources by means of ubiquitous Web and Java technologies and creates an electronic spot market focused on the mainstream Internet user as suppliers of idle computing resources. We introduce the economic Price/Market model of Locust enabling the export or import of resource surpluses or lacks between so-called submarkets. Test cases for consumption of aggregated CPU resources include distributed Raytracing and RC5 decryption. We further describe the RC5 key block management and our efforts to reach performance comparable to native RC5 implementations.
