Performance of the MPI Based File Share System

Abstract

The current Internet traffics depend more on the P2P type communication than the legacy client-server type communication. The P2P communication has been applied to diverse systems such as the VoIP and the file sharing system for the P2P potential ability. The distributed file sharing system over the P2P network can especially provide the quick search, while the file accesses from the remote user do not follow the uniform distribution causing the degradation of searching performance. In this paper, we propose the new framework to implement the access method of shared objects into the real environment using the MPI (Message Passing Interface). In addition, we implemented the conventional Lock/Unlock method using MPI to compare the proposed owner permission method to access shared objects. The proposed shared object management system implemented on the MPI middleware can improve the processing speed compared to the Lock/Unlock method.
