Job Management System

Job Management is used for the purpose of strengthening the batch processing of operating system, providing the mechanism of submitting, scheduling, executing and controlling jobs, and hence taking more effective use of the resources in the system, implementing load balance, improving the performance of the whole system. Since the Network Queuing System (NQS) came into being, the job management system has made great improvement. Many large research organizations and corporations have been using job management systems as an important warranty of improving productive efficiency and promoting ratio of resource usage; lots of researches and development have been carried out according to the actual need. However, the domestic research in this field hasn't been carried out extensively and deeply.The author has taken part in an international project-the research and development of the server to job management system. Based on the recent two years' experience the author has gained a deep recognition about the architecture of job management system. This thesis summarized the research product of the author's two year's project experiment.1) Gave an overall analysis of the Job management system's frame and function description of the parts in the frame in detail. Put forward the tree-tired architecture of job management system. Based on the deep analysis of the modules made function improvement to some of them.2) Improved the mechanism of submitting job network automatically , thus tasks that have to be performed regularly - such as collecting daily transaction data, creating daily reports, and generating monthly reports - can be automated and streamlined as much as possible so that enterprises can make better use of their valuable human resources; I designed the mechanism of monitoring job network trackers of multiple computers. Realized the import and export function of job network file, so the job network can be defined once and used everywhere. I resolved the memory leak problem of several main service programs. 3) Did deep research on the algorithm and implements of job disperse and job scheduler. Based on the discussion and analysis of the factors that influence the load balance I designed the job celerity equilibrium algorithm based on dynamic rules. Discussed several dynamic job disperse methods.
