Research And Implementation Of Complex CAE Job Management System Based On SuperComputing

After entering the 21 st century,the development trend of the global information technology,which take high performance computing as the forerunner,is swift and violent.Supercomputer Center is considered as important infrastructure to promote the development of modern science and information technology,which has received the widespread attention and has become important means of scientific and technological innovation in some developed countries and regions,such as European and American.Super computer possesses the powerful computer function ?the fastest operating rate and the largest storage capacity,which is used to solve the computational problems of high-tech and cutting-edge technology research.In the field of industrial design simulation,CAE technology is one of the main means of innovative development for many industrial enterprises and is one of the primary measure marks of industrial enterprise innovation ability.However,when using CAE technology to carry out innovation research,we need large-scale computer system?all kinds of expensive specialty numerical calculation software and the calculation simulation engineer.Sometimes,even the big enterprise,they cannot completely has the above research resources to meet the needs.In the field of industrial design,CAE simulation application needs to use the supercomputers to do large-scale parallel computing,such as the whole machine mechanical analysis and the joint simulation of the electromechanical liquid after the large and complex CAD design.This paper studies the complex CAE job management system in the supercomputing environment,which allows the user to conveniently and efficiently use super computer to carry on the simulation of the CAE job replication.This article main work includes:First of all,we introduce the "Tianhe No.1" supercomputer,analyze CAE operation simulation process,study the SLURM scheduler principle and analyze the SLURM job management system.Secondly,in order to solve the order and single inefficient way of complex collaborative CAE assignments submission in the past.This paper proposes a complex CAE job scheduling algorithm based on the DAG clustering,and implements the scheduling strategy based on SLURM sch eduling principle.Results show that the proposed scheduling strategy increases the use efficiency of the super computing resources.Finally,the paper introduces the demand and design of the job management system based on super computer complex CAE work a nd implements the job management system in the supercomputer environment.Based on the CAE simulation of earth pressure balance shield machine,we carry out test verification from the job submission?the operation monitoring? the operation retrieve and the homework post-processing process of job management system.Practice shows that the complex CAE job management system based on the supercomputer environment has great practical value for the CAE simulation field of industrial design in this paper.It reduces t he complex CAE simulation difficulty for users and makes full use of the supercomputer computing resources.
