A market-based scheduler for JXTA-based peer-to-peer computing system

Abstract

Peer-to-Peer (P2P) computing is said to be the next wave of computing after client-server and web-based computing. It provides an opportunity to harness a lot of idle peer-resources such as desktop computers across the Internet, for solving large-scale computing applications. Each peer is autonomous and it needs incentive for sustained contribution of its resources to P2P applications. In addition, a flexible and efficient job scheduling is needed to harvest the idle computing power as cheaply and economically as possible. This paper introduces an economic based job scheduler for mapping jobs to resources in P2P computing environment. The scheduler has been implemented with the Compute Power Market (CPM) system developed using Sun JXTA P2P technology. Our scheduler can be configured depending on users' quality of service requirements such as the deadline and budget constraints. Our scheduler follows a hierarchy scheme. The design allows multiple consumers and multiple providers to schedule and run jobs. To allow wider support for a wide variety of applications, the system is designed to allow easy 'plug in' of user applications. © Springer-Verlag Berlin Heidelberg 2004.
