AGENT P2P-MPI MIDDLEWARE AND METHOD FOR DESIGN THE SAME

摘要

Agent-based P2P(Peer-to-Peer)-MPI(Message Passing Interface) middleware and a design method thereof are provided to odder a volunteer availability-based grouping technique for guaranteeing stable computation in a P2P-based distributed system environment and offer an algorithm for improving computation reliability through availability-based duplication. A first library is generated by applying a method for calculating a computation time ratio of each volunteer in the P2P-based distributed system and a computation availability ratio representing computation joining probability of each volunteer(S30). A second library is generated by applying an overlay networking method(S34). The overlay network method classifies the volunteers according to the computation time/availability ratio, assigning an ID key to each volunteer, selects the volunteer having the high computation time/availability ratio as a coordinator, and forms a resources ID tree with the coordinators and the volunteers. A third library is generated by applying a computation duplication technique(S36). A fourth library is formed by coding computation dependency into an XML(eXtensible Markup Language) code(S38).
