PCP: P2P-based computing resource sharing and aggregation platform

A P2P-based computing resource sharing and aggregation platform called PCP was developed and constructed in this paper.PCP is a platform harnessing the immense computational resources available in the Internet for parallel and distributed computing.PCP platform is peer-to-peer based,easy to use and efficient.These features are strongly supported by a network overlay over which peers can communicate with each other.The authors made use of a general-purpose P2P library,JXTA,supporting the common requirements of P2P software,including network overlay.Other features of the P2P library,such as Ad Hoc self-organization,discovery and grouping of peers,also support PCP efficiently.A parallel programming library was also presented in PCP by JXTA communicating library.A volunteer node can submit and monitor the parallel applications by job management subsystem to complete the whole computation.The results obtained from performance analysis show that the throughput and speedup ratio of PCP are better in master-slave style parallel applications.
