Distributed Optical Transmission Simulation System

Supported by the theory of laser transfer simulation computing and computer science, traditional laser transfer simulation computing software that is mainly used on a single computer have become a major tool to solve general design and optimization problem about our second generation high power solid laser driver SG III antetype equipment. Developing a distribute compute system is a useful method to improve computing speed, use the computation ability in the network sufficiently and improve the ability to solve large scale problem.Distribute compute technique is one of the most active factors which affect the development of compute technique. Client-Server pattern is the mainstream method to construct the distribute compute system, it can implement the resource share in the network and has flexible system structure and favorable extensibility. But this pattern can't offer ability to keep the servers' load equilibrium and the error tolerance is limited. So with the reference of the three tires structure in the MIS system, we introduce a middle server which can finish the tasks about user authentication and tasks distribution to offer transparent compute service. Using the queue about compute resource we can solve the load equilibrium problem and avoid the user refer their compute task to a invalide server and improve the error tolerance ability.Laser transfer simulation computing system includes preprocess(laser transfer model),physical model, message passing, file transfer, computing process control and postprocess(visualization and analysis).Message passing, data file transfer and process control are the key problems, it is the base to achieving the connection, the mutual operation and the cooperative work between the independent computers.This research's characters and novelty are listed below:.Point out the method to build a client-server computing pattern with tree tier architecture to solve the compute servers' load equilibrium and error tolerance ;.According to the characteristic of the data in laser transfer simulation computing, a transmission protocol is defined. With the help of the socket programming technique that supports the TCP/IP protocol, implement the point-point file transfer and message passing between client and server;.Point out and present distributed laser transfer simulation computing system with tree tier architecture...
