摘　　要：描述了一个基于非结构化对等网络、可以共享网络上空闲资源的JVMs虚拟机的桌面网格平台UDDG(unstructureddecentralized desktop grid)。提出了对等实体的最小活跃邻居节点数、更新时间域值等概念,每个对等实体维护了一个最小活跃邻居数的列表,结合非结构化对等网络的网络跳数的机制,通过广播查找消息来寻找资源的虚拟机。通过构建评测环境,运行并行案例程序计算结果表明,UDDG提供了一种构建高性能的桌面网格平台的新思路。An unstructured peer-to-peer based decentralized desktop grid platform called UDDG which can share the available PC terminals over the Internet for parallel and distributed computation transparently and seamlessly is described and implemented.Like unstructured approaches we propose that each peer maintains a list of acquaintances and also some modifications to the basic flooding protocol to make the platform scalable.At last,UDDG is deployed as a permanent desktop grid,with which we have achieved a computation record by solving the NQueens problem.The results obtained fromperformance analysis shows thatUDDG is feasible and efficientwhich can provide a new way for building grids.
