The Virtual Reality System of the Humble Administrator's Garden

The article discusses the process of making the Virtual Reality System of the Humble Administrator's Garden.It also discusses how to apply Virtual Reality to the Architecture design in current functions in hardware and software. Key words:3D computer animation;Virtual Reality;VRML;Application states within cluster system. Since the cluster system availability mainly lies on nodes' probability distribution of Time Between Failure and Time To Repair, we give random variable's probability distribution and sampling method of nodes in the cluster system. On the basis of identifying the failure state and repair state of nodes, we can determine the cluster system working state. According to failure and repair experience, this paper gives simulation result when Time Between Failure is assumed exponentially distribution(a single parameter distribution), while the Time To Repair is considered to be lognormally distributed(a two parameter distribution). However, other distribution can easily be substituted. Thus, the objectives, methodology, logic, and significant features of the simulation are described in detail, and the algorithm and computer program is developed to estimate the availability through simulation. It can provide a quantitative foundation for the analysis and design of cluster system's availability.
