Autonomic Resource Management for a Cluster that Executes Batch Jobs
MetadataShow full item record
Resource management of large scale clusters is traditionally done manually. Servers are usually over-provisioned to meet the peak demand of workload. It is widely known that manual provisioning is error-prone and inefficient. These problems can be addressed by the use of autonomic clusters that manage their own resources. In those clusters, server nodes are dynamically allocated based on the system performance goals. In this thesis, we develop heuristic algorithms for the dynamic provisioning of a cluster that executes batch jobs with a shared completion deadline. <br /><br /> External factors that may affect the decision to use servers during a certain time period are modeled as a time-varying cost function. The provisioning goal is ensure that all jobs are completed on time while minimizing the total cost of server usage. Five resource provisioning heuristic algorithms which adapt to changing workload are presented. The merit of these heuristics is evaluated by simulation. In our simulation, the job arrival rate is time-dependent which captures the typical job profile of a batch environment. Our results show that heuristics that take into consideration the cost function perform better than the others.
