Design And Implementation Of CAE Resources Integration Cloud Platform Front-end System In The Super-computing Environment

Into the 21st century,With the rapid development of information technology guided by petaflop supercomputers,the Supercomputing Center,as an important infrastructure of promoting modern information technology,has attracted substantial attention recently.Many countries are actively constructing their public service platforms based on supercomputers which have the ability of resource sharing and are fully functional and available to the society.Furthermore,building a simulation platform based on the supercomputers for industrial designing and integrating is viewed as a particularly important part of industrialization strategy.However,existing supercomputing platforms interact with users through a command-line model,which can only be operated by professionals.This obviously obstacles its promotion to the market and challenges the widespread application of supercomputing platforms.Therefore,it is critical to design a cloud platform,which provides integrated CAE resources as services to users.The study objects of this paper are as follows:(1)Construct a "Supercomputing Integration Platform" portal system.The system unifies all of its subsystems for various users,i.e.,it provides an external portal for general public users and an internal portal for the staffs of the supercomputing center.(2)Build a remote job submission and monitoring system.In the system,each job is classified according to its corresponding project and reclassified by the solver which will be used to finish this job.This solves the problem of encryption and decryption on remote data transmission,long-term large file transmission and excessive data processing obtained from real-time monitoring.(3)Construct a remote resource management and control system.This system can obtain computing resources(e.g.,CPU,GPU)of supercomputers and their utilization through real-time communication with clusters.Obtained information can be displayed graphically in a specified time area.It can also monitor the utilization of software licenses,historical and current resources and network status.It helps improving the efficiency of resources utilization according to job scheduling strategies.(4)Propose the idea of integrating the authentication of users' behavior into the front end system in cloud computing and research on Petri nets,dynamic game theory.Finally,establish an integrated security management and control system which unifies all the sub security systems.The main innovations are the idea of integrating the authentication of users' beh avior into the front end system,the remote monitoring and control on resources of "T ianhe 1" and the graphic display of the monitoring results.
