Future Generation Computer Systems Special issue on Peer-to-Peer Computing and Interaction with Grids Submission deadline: July 1, 2003. Topics of the Special Issue Peer-to-Peer environments are characterized by large scale (thousands to millions of participants), intermittent user and resource participation, lack of trust, and lack of centralized control. Designing mechanisms for Peer-to-Peer (P2P) environments proved to be a stimulating research problem that led to remarkable results in scalability, robustness, location, distributed storage, and system measurements. A less addressed and more challenging problem is computing in a P2P environment: computation is notoriously hard to distribute, yet the potential of harnessing millions of computers is tremendous. Grid computing focuses on distributing computation on wide-area collections of shared resources. P2P and Grid systems share the same focus on harnessing resources across multiple administrative domains, but they differ in many respects: Grids address support for a variety of (usually, scientific) applications and hence focus on providing infrastructure to moderate-sized, homogeneous, and partially trusted communities. In contrast, P2P systems concentrate on providing support for intermittent participation in vertically integrated applications for significantly larger communities of untrusted individuals. This special issue of Future Generation Computer Systems is dedicated to recent advances in P2P computing and the relevant lessons from Grid computing. Topics of interest include, but are not limited to: * Management of computational resources in large, unreliable networks * Incentives for computing in P2P environments * Applications for P2P computing * Infrastructure for supporting computation in P2P environments * Trust and security in P2P computing * Lessons from Grids (P2P) relevant to P2P (Grid) computing * Algorithms for computing in P2P environments * Grid Services and Peer to Peer * Peer to Peer protocols for the Grid Paper Submission We invite you to submit a full paper of up to 15 pages describing new and original results or a survey on a specific topic.
