Research And Implementation Of Job Management System Based On Super-Computing Environment For CAE Simulation Platform

In recent years,China's supercomputer technology has developed rapidly while high-performance applications are still in low-level.The use of CAE simulation technology for scientific computing often requires a lot of computing capacity to solve complex big data processing algorithms,but whether high-performance computer or CAE software have highly initial purchase and maintenance costs,which is too high for some researchers to use.In this paper,a job management system for CAE Simulation Platform designed and implemented based on the super-computing environment,the purpose is to allow users from business and universities use the system via the Internet environment,and can do the product design,analysis,calculations,and simulations in industria,thus can accelerate adoption rate for using CAE technology in industrial.The main work as follows:Firstly,we have an in-depth study of the current research CAE simulation job management system,and combe business processes of the CAE simulation jobs,design CAE simulation platform for cloud operating system architecture,service model and service processes based on the idea of three-tier architecture of cloud computing services.Secondly,we implemente a prototype of CAE simulation jobs based on supercomputing:the user does not need to familiar with high-performance computer systems;CAE simulation can submit jobs via an interactive browser.Meanwhile,in order to solve the existing scheduling model flexibility which the algorithms are unable to provide personalized service scheduling problems,propose a job scheduling algorithm to improve the user experience based on user behavior,management decision and Improve utilization of system resources.Finally,we give an example of a balloon-type buffer structure Mars lander CAE simulation process,illustrate process from user login,job generation,job submission,the model solving,the outcome document retrieval,which verifies the system's processing business functions and reflects the system's value.CAE simulation job management system allows users with large number of simulation demand can be more easily done with large specification of complex CAE analysis,reducing CAE technical barriers.To some extent,can solve some enterprises issue and realize the value of supercomputers.
