Enhancements to the Decision Process of the Self-Tuning dynP Scheduler
The self-tuning dynP scheduler for modern cluster resource management systems switches between different basic scheduling policies dynamically during run time. This allows to react on changing characteristics of the waiting jobs. In this paper we present enhancements to the decision process of the self-tuning dynP scheduler and evaluate their impact on the performance: (i) While doing a self-tuning step a performance metric is needed for ranking the schedules generated by the different basic scheduling policies. This allows different objectives for the self-tuning process, e. g. more user centric by improving the response time, or more owner centric by improving the makespan. (ii) Furthermore, a self-tuning process can be called at different times of the scheduling process: only at times when the characteristics of waiting jobs change (half self-tuning), i. e. new jobs are submitted; or always when the schedule changes (full self-tuning), i. e. when jobs are submitted or running jo...
