A P2P-based high performance computing platform

Based on peer-to-peer networks and composed of a Portal,a Datapool,a workbench and many work groups,P2HP-2 is a high performance distributed computing platform,which supports applications with task-level parallelism.Users communicate with the platform through the Portal and the task data of applications are stored in the Datapool.The workbench assists to maintain the platform and schedule tasks on it.Computers which are physically neighbored with each other in the network assemble together to form a work group,in which members collaborate to finish computing tasks.All the work groups communicate with each other through the routing protocol which are self-organized and structured as a group-based peer-to-peer network,called as GTapestry.The design of the architecture of P2HP-2 and research on its applications are presented in this paper.Also combined with applications,the performance of P2HP-2 is analyzed.
