Reseach On Marching-on In-time Scheme And The Fast Algorithm Of Time Domain Integral Equation

In computer technology make a spurt of progress of the times, the continuous development of virtualization technology, in order to rationalize the management to realize the data center virtualization, cluster technology is applied more and more widely. The emergence of the cluster technology, greatly improving the utilization rate of data center resources, significantly reduces the data center management and maintenance costs, improve the efficiency of high availability and service management, ensure to provide uninterrupted service. This paper introduces the main content is to design and implement an available cluster management system. Including two subsystems including: cluster configuration management subsystem, resource and service management subsystem.This article from the whole function of cluster management system needs analysis design and Realization of two subsystems, namely the cluster configuration management subsystem and resource service management subsystem. The main function of the cluster configuration management subsystem which is the management of cluster system configuration file, the main function of the resource group management subsystem is to realize monitoring, to the service to start, stop and transfer functions such as operation; this follows a modular design ideas, clear module division, define a call library interface module and the upper communication protocol. Finally set up the testing environment, the completion of the basic case of functional verification test.In the process of research and development of the cluster system, according to the demand of the product, simply realize the basic functions of characteristics of virtual machine resource and service management related to the operation and management of the cluster configuration, so as to realize the effective management of the virtual machine, provides excellent support to improve cluster high availability features, and also optimized configuration management system, the realization of the configuration file to load, so that the system can more intelligently manage configuration files.
