CUC 2004 F2 Emir Imamagić, Dobriša Dobrenić, Branimir Radić - Job Management System Analysis
Job Management System (JMS) is a system responsible for control over user jobs and cluster nodes. Main objective of JMS is to achieve maximal utilization of cluster resources, while satisfying users needs. JMS is also known as Resource Management System, Workload Manager and Batching System. JMS has three basic functionalities: queuing, scheduling and resource management. Functionalities are implemented in following three JMS modules: Queuing Server, Scheduler and Resource Manager. Server is responsible for job queuing and interaction with users. Scheduler makes decisions where will the jobs be executed. Decision is based on various types of policies. Resource Manager monitors resources and jobs, allocates resources for jobs and prepares environment for job execution. Furthermore, Resource Manager notifies Server of resource and job status.
