Research On The Resource Management And Task Sechedule For The Distributed Simulation Platform

Distributed computing is a branch of computer science. It studies how to divide a task which needs a huge computing ability into many sub-tasks, distribute these sub-tasks into a plurality of computers, and get the results of the task; The simulation use the computer to simulate the process of a real system, and use the project model to transform the uncertainty of a project into the influence of the goal. Simulation can be done through distributed system which is called distributed simulation system, through this system, the speed of the simulation process is speed mostly. Usually, in distributed computing system, the model of the simulation is very complex, which leads to more comlicated opearion should be done. so an intuitive, practical man-machine interface is a reasonable choice.Based on the study of the architecture for digital simulation of high-speed train, a special resource management and task scheduling subsystem is provided in this paper. The system uses the graphical modeling method to construct the system model, and then finish the works of simulation by distributed system. The simulation system adopts the structure of client/server mode, which including:resource management and the task scheduling server, couplers, executive machine. Execution machine for simulation is the computing unit, all the simulation calculation will be excuted by the executive machine. And execution machine recieve the data they need from or send the result to the couplers. Resource management and the task scheduling server is responsible for management simulation task, which are assigned to execution machine. This design mainly completed one of the resource management and the task scheduling subsystems, including the graphical modeling system of the simulation.This thesis mainly divided into three sections. The first part is the introduction, which mainly discussed the research subject academic background, theoretical and practical significance, research brief, the researching purpose and the researching method; The second part is the requirement analysis, introducing the resources management and the main functions of the task scheduling subsystem and the main objectives of the researching; The third part is the overall design, this paper introduces the system structure and software various part of main function; The fourth part is for the details of the system designing, and this part introduces the general design of the function realization process and achieving results. The last part is to prefer the test works of the systems, and summarized the work of this paper.
