Two-level Scheduling Mechanism Supporting Real-time Cluster System
Shuyu Chen · 2008
We propose a real-time scheduling mechanism in cluster system,which provides real-time priority services by combining load balancing scheduling in front-end and scheduling algorithm based on length difference between real-time and non-real-time task queue in back-end.The new scheduling mechanism increases the utilization of cluster nodes in case of scheduling only in front-end and enhances the response of real-time tasks.As is shown in the comparison experiments,the response time of real-time tasks is decreased observably under the condition of generating guaranteed throughput,the mechanism provides a viable reference for the designing of distributed real-time scheduling.
